[SR-Users] slow timer too slow: overflow

[Daniel-Constantin Mierla]

Hello,

I would also worry about the out of memory logs. For troubleshooting in
such case, you need to get:

kamctl ps

kamctl rpc pkg.stats

Maybe also you set latency limits via core parameter to see if some
operations are slow in the config.

If there are slow C functions run internally on timer, then maybe you
can troubleshoot with debug=3.

Cheers,
Daniel
