Firmware v4.9 Preview: What to Expect

will.qiu · June 2, 2026, 1:49am

Hi

A significant increase in memory usage while updating DNS filter lists is expected behavior in AdGuard Home, including the latest v0.107.76 release (see the Github issues below):

### Prerequisites - [X] I have checked the [Wiki](https://github.com/AdguardT…eam/AdGuardHome/wiki) and [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions) and found no answer - [X] I have searched other issues and found no duplicates - [X] I want to report a bug and not ask a question ### Operating system type Linux, OpenWrt ### CPU architecture AMD64 ### Installation GitHub releases or script from README ### Setup On a router, DHCP is handled by the router ### AdGuard Home version v0.108.0-a.466+9f7a582d ### Description #### What did you do? Installed AGH on router and set filters to update every 24h. Filters are saved in /opt (not RAM) trying to use less RAM, also logs are reduced to spare RAM. #### Expected result While using around 250MB of RAM for AdGuardHome only, the router usually still has more than 70 MB of free RAM. AdGuardHome should manage the available RAM to update filters without crashing. #### Actual result "top" command shows that AGH is reserving 932 MB when there are 406 MB usable (229% of VSZ). When comes the time to update filters, AGH tries to allocate 932 MB and then it invokes oom-killer on itself due to lack of free RAM. #### Screenshots (if applicable) ![openwrt](https://user-images.githubusercontent.com/55603581/226075267-233717e0-47dd-4355-adaa-bc4ec42575cd.png) ``` [ 61.700658] AdGuardHome invoked oom-killer: gfp_mask=0x1100dca(GFP_HIGHUSER_MOVABLE|__GFP_ZERO), order=0, oom_score_adj=0 [ 61.700723] CPU: 0 PID: 5074 Comm: AdGuardHome Not tainted 5.15.98 #0 [ 61.710610] Hardware name: Xiaomi AX3600 (DT) [ 61.717031] Call trace: [ 61.721365] dump_backtrace+0x0/0x180 [ 61.723627] show_stack+0x18/0x30 [ 61.727445] dump_stack_lvl+0x6c/0x88 [ 61.730743] dump_stack+0x18/0x34 [ 61.734389] dump_header+0x44/0x180 [ 61.737687] oom_kill_process+0x1e0/0x1e4 [ 61.740987] out_of_memory+0x1c8/0x2fc [ 61.745153] __alloc_pages_slowpath.constprop.0+0x82c/0xa44 [ 61.748803] __alloc_pages+0x210/0x25c [ 61.754268] alloc_zeroed_user_highpage_movable+0x24/0x30 [ 61.758091] wp_page_copy+0x378/0x88c [ 61.763556] do_wp_page+0xa0/0x434 [ 61.767200] __handle_mm_fault+0x69c/0xa70 [ 61.770500] handle_mm_fault+0x148/0x1f0 [ 61.774580] do_page_fault+0x14c/0x3e0 [ 61.778660] do_mem_abort+0x44/0xb0 [ 61.782218] el0_da+0x24/0x60 [ 61.785603] el0t_64_sync_handler+0xac/0x114 [ 61.788731] el0t_64_sync+0x184/0x188 [ 61.793138] Mem-Info: [ 61.796632] active_anon:67573 inactive_anon:42 isolated_anon:0 [ 61.796632] active_file:170 inactive_file:28 isolated_file:0 [ 61.796632] unevictable:0 dirty:0 writeback:0 [ 61.796632] slab_reclaimable:1701 slab_unreclaimable:9055 [ 61.796632] mapped:25 shmem:20 pagetables:362 bounce:0 [ 61.796632] kernel_misc_reclaimable:0 [ 61.796632] free:4878 free_pcp:146 free_cma:0 [ 61.811694] Node 0 active_anon:270292kB inactive_anon:168kB active_file:680kB inactive_file:112kB unevictable:0kB isolated(anon):0kB isolated(file):0kB mapped:100kB dirty:0kB writeback:0kB shmem:80kB writeback_tmp:0kB kernel_stack:2160kB pagetables:1448kB all_unreclaimable? yes [ 61.835988] DMA free:19512kB min:16384kB low:20480kB high:24576kB reserved_highatomic:0KB active_anon:270276kB inactive_anon:168kB active_file:72kB inactive_file:472kB unevictable:0kB writepending:0kB present:524288kB managed:416628kB mlocked:0kB bounce:0kB free_pcp:584kB local_pcp:256kB free_cma:0kB [ 61.862645] lowmem_reserve[]: 0 0 0 0 [ 61.884844] DMA: 647*4kB (UME) 421*8kB (UME) 265*16kB (UME) 66*32kB (UME) 19*64kB (UME) 8*128kB (UM) 6*256kB (UME) 2*512kB (UM) 2*1024kB (M) 0*2048kB 0*4096kB = 19156kB [ 61.888502] 215 total pagecache pages [ 61.903598] 0 pages in swap cache [ 61.907176] Swap cache stats: add 0, delete 0, find 0/0 [ 61.910458] Free swap = 0kB [ 61.915474] Total swap = 0kB [ 61.918628] 131072 pages RAM [ 61.921475] 0 pages HighMem/MovableOnly [ 61.924330] 26915 pages reserved [ 61.927889] Tasks state (memory values in pages): [ 61.931372] [ pid ] uid tgid total_vm rss pgtables_bytes swapents oom_score_adj name [ 61.936003] [ 732] 81 732 344 30 32768 0 0 ubusd [ 61.944523] [ 733] 0 733 226 9 32768 0 0 askfirst [ 61.952762] [ 768] 0 768 263 16 28672 0 0 urngd [ 61.961248] [ 1285] 514 1285 332 21 32768 0 0 logd [ 61.969307] [ 1345] 0 1345 941 131 32768 0 0 rpcd [ 61.977477] [ 1802] 0 1802 690 26 40960 0 0 hostapd [ 61.985547] [ 1803] 0 1803 690 26 40960 0 0 wpa_supplicant [ 61.993620] [ 1817] 101 1817 780 52 40960 0 0 hostapd [ 62.002646] [ 1818] 101 1818 760 32 40960 0 0 wpa_supplicant [ 62.010895] [ 1867] 0 1867 515 52 32768 0 0 netifd [ 62.019913] [ 2148] 0 2148 405 29 32768 0 0 odhcpd [ 62.028190] [ 2207] 0 2207 328 13 28672 0 0 crond [ 62.036421] [ 2273] 0 2273 688 35 32768 0 0 uhttpd [ 62.044691] [ 3439] 0 3439 276 16 32768 0 0 dropbear [ 62.052853] [ 3835] 0 3835 690 28 36864 0 0 dnsmasq [ 62.061444] [ 3845] 453 3845 1179 97 40960 0 0 dnsmasq [ 62.069628] [ 4645] 0 4645 255774 66712 692224 0 0 AdGuardHome [ 62.077846] [ 4791] 0 4791 341 24 28672 0 0 sh [ 62.086503] [ 4915] 0 4915 690 28 40960 0 0 ntpd [ 62.094493] [ 4937] 123 4937 327 14 32768 0 0 ntpd [ 62.102745] [ 5095] 0 5095 341 28 28672 0 0 sh [ 62.110844] [ 5096] 0 5096 327 13 32768 0 0 logger [ 62.118545] [ 5113] 0 5113 327 9 28672 0 0 sleep [ 62.126806] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/,task=AdGuardHome,pid=4645,uid=0 [ 62.135075] Out of memory: Killed process 4645 (AdGuardHome) total-vm:1023096kB, anon-rss:266848kB, file-rss:0kB, shmem-rss:0kB, UID:0 pgtables:676kB oom_score_adj:0 [ 95.885732] IPv6: ADDRCONF(NETDEV_CHANGE): phy1-ap0: link becomes ready [ 95.885960] br-lan: port 5(phy1-ap0) entered blocking state ``` ``` PID PPID USER STAT VSZ %VSZ %CPU COMMAND 7479 1 root S 932m 229% 0% /usr/bin/AdGuardHome -c /etc/adguardhome.yaml -w /opt/AdGuardHome -s run --no-check-update ``` #### Additional information Right now it's running edge build, but it also happens with beta build and with v107. The problem seems to be AGH trying to blindly allocate 930 MB of RAM when it should instead check how much free RAM there is (more than 70 MB) and manage to update the filters with it. I suppose 70 MB should be plenty RAM to update any lists.

High memory and CPU usage

### Prerequisites - [x] I have checked the [Wiki](https://github.com/AdguardTea…m/AdGuardHome/wiki) and [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a) and found no answer - [x] I have searched other issues and found no duplicates - [x] I want to report a bug and not [ask a question or ask for help](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a) - [x] I have set up AdGuard Home correctly and [configured clients to use it](https://github.com/AdguardTeam/AdGuardHome/wiki/Clients). (Use the [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a) for help with installing and configuring clients.) ### Platform (OS and CPU architecture) Linux, AMD64 (aka x86_64) ### Installation Other (please mention in the description) ### Setup On one machine ### AdGuard Home version v0.107.73 ### Action High memory and CPY usage during a couple of hours every day. This issue started after upgrading to "v0.107.73". I have 512mb allocated to AdGuard Home and have never had this issue before the upgrade. RAM usage is normally around 300mb and for CPU, below 1% The high usage starts at around 9-10pm (09:00-10:00). I can see small peaks before the upgrade but never to this extent. <img width="1205" height="719" alt="Image" src="https://github.com/user-attachments/assets/7f82b3dd-165d-4d09-91ff-558a0d08c263" />
