[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,

I do not use puke.top rpc command. Maybe this issue related to TLS? Servers
what has this problem are utilizing TLS heavily, servers which do not has
this problem use UDP.

With kind regards,

Jurijs
