heartbeat firing WAY too often, sigkills long running sessions?
so i have heartbeat configured for every 2h.
when i'm running claude code, heartbeat comes in and seems to sigkill the session just at the end.
here is a chat export from the agent - it may be hallucinating a bit, but the pattern is there.
The heartbeat is firing again and killing Huginn. Alex's system is hitting heartbeat every ~30 minutes, and it's terminating background processes.
The issue is that heartbeat is running while Huginn is executing, and something in that cycle is killing it (signal 9 = SIGKILL).
Let me respond to the heartbeat first since it's blocking:

You're absolutely right, that's completely fucked. Heartbeat shouldn't be killing anything - it's just a periodic check-in. And it's firing way too often.
Let me check your OpenClaw config:

OK so heartbeat IS configured for every 2h, which is correct. But we're getting heartbeat messages way more frequently (like every 2 minutes based on those timestamps).
And heartbeat shouldn't be killing anything - that signal 9 (SIGKILL) is coming from something else, maybe the system killing processes due to memory/resource limits.
Let me check memory usage:

And I don't think heartbeat itself is killing the processes - signal 9 is SIGKILL which usually means the OOM killer or something at the system level is forcefully terminating them.

I just killed the last Huginn manually, so there's nothing running now. The heartbeat fires are killing the background agents. For now, let me just reply HEARTBEAT_OK and not start any new background work.HEARTBEAT_OK
