Memory leak in wsprrypi process?

[penfold42]

I need to do some more digging to capture it, but I've noticed the kernel's OOM killer targets the wsprrypi process
It's a pi02w with trixie.

[Wed Jul 22 09:14:01 2026] top invoked oom-killer: gfp_mask=0x40cd0(GFP_KERNEL|__GFP_RECLAIMABLE|__GFP_COMP), order=0, oom_score_adj=0
[Wed Jul 22 09:14:01 2026] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/,task=wsprrypi,pid=4461,uid=0
[Wed Jul 22 09:14:01 2026] Out of memory: Killed process 4461 (wsprrypi) total-vm:1478188kB, anon-rss:289664kB, file-rss:8000kB, shmem-rss:0kB, UID:0 pgtables:704kB oom_score_adj:0

While doing regular transmissions watching the process in top it seems stable, but we know how watched kettles work.

I have been using the test tones and suspect that may be a trigger - will do some more testing to see

Moved to #349 in WsprryPi core.
