I have two piholes, both on Pi-Zero Ws, that have FTL crashing or being killed due to out of memory.
The below is from kern.log:
May 11 07:24:34 hera kernel: [1035697.857225] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),global_oom,task_memcg=/,task=pihole-FTL,pid=17924,uid=999 May 11 07:24:34 hera kernel: [1035697.857317] Out of memory: Killed process 17924 (pihole-FTL) total-vm:485988kB, anon-rss:349412kB, file-rss:0kB, shmem-rss:924kB, UID:999 pgtables:452kB oom_score_adj:0 May 11 07:24:34 hera kernel: [1035698.595688] oom_reaper: reaped process 17924 (pihole-FTL), now anon-rss:0kB, file-rss:0kB, shmem-rss:924kB
Restarting DNS temporarily resolves the issue. I restarted DNS immediately before generating the debug log.
Let me know if there's anything else you need to help troubleshoot. Thanks.
Expecting FTL to continue running.
FTL is crashing.
