[OpenSIPS-Users] Opensips 1.10.1 stopped to process SIP messages

[dpa]

Hello!

 

Today there was one problem.

Opensips stopped to process SIP messages during about 2 minutes.

 

Log analyses of problem`s time period shows some "unusual" messages

 

<ERROR:core:udp_send: sendto(sock,0x7fd068403ad0,35904,0,0x7fff63d1ddd0,16):
No buffer space available(105)

ERROR:aaa_radius:send_auth_func: radius authentication message failed with
TIMEOUT

rc_send_server: no reply from RADIUS server unknown:1812

rc_ip_hostname: couldn't look up host by addr: D5AA5098

> 

 

Opensips during call processing interacts with radius server (and there was
some problem with radius server during problem`s time period). It was done
for prepaid scheme (although not all clients use prepaid)

During problem`s time period there were a lot of messages

<BYE has been sent because of dialog lifetime = 10>

It`s my own. Xlog (function located in local route of the opensips.cfg)
generates this message if Opensips terminates dialog for some reason. 

"lifetime = 10" means that "modparam("dialog", "default_timeout", 10)"
expired and there were no ACK on 200 OK. 

And ngrep shows that 200 OK had not translated to caller by Opensips during
problem`s time period.

 

After radius server UP ( and "rc_send_server: no reply from RADIUS server
unknown:1812" and "rc_ip_hostname: couldn't look up host by addr: D5AA5098"
disappeared) Opensips became work normally. 

 

What can it be? And how can I avoid such problem in future?

 

Thank you for any help.
