[SR-Users] Out of memory in UB 210: OOM killed process 12261 (kamailio) score 0 vm:1614768kB, rss:280200kB, swap:131408kB

[Jurijs Ivolga]

Hi Daniel,

After 8 days there is still small memory leak, 200MB of Ram wasn't freed
during this 8 days, please check diagram below.

1) Is this something usual?
2) Memory leak seems very small, maybe I should never worry about this?
What you think?

Thank
you!

With kind regards,

Jurijs
