gnugk 2.2.6 in full routed mode - rtcp ports leakage?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello all,

during last few days my setup of gnugk got into some trouble. At some
point gnugk gets full of opened udp ports with reasonable number of
current calls, and could not open any more because of the limits
enforced at compile time (large_fdset=4096). At this point log is full
of lines:

2007/06/11 18:41:28.449 1       ProxyChannel.cxx(3802)  RTP     RTCP
socket xx.xx.xx.67:55821 not available - error 7/24: Cannot allocate
memory

To confirm the shortage of sockets, I've did "lsof -n -p <gnugk pid>"
and counted lines with "wc -l", which was exactly 4096.

Restart of gnugk resolved the trouble, but it does take like 20-30
hours till it gets full of udp open ports again. Taking a look at the
number of open ports shows more or less linear growth. Recompiling
with bigger large_fdset value will only postpone the moment of gnugk
getting stuck.

Can I have any hints what should be checked and how? I could build
"debug" version of pwlib 1.10.7, openh323 1.18.0 and gnugk, if that
comes handy.
