[SR-Users] slow timer too slow: overflow

[Denys Pozniak]

Hello!

After some time, Kamailio stops processing incoming messages.
slow timer too slow: overflow messages appear in the log (I suspect that
the problem is related to the rtimer module)

Please point me out where the source of the problem could be.

version: kamailio 5.6.1 (x86_64/linux)
