Hi All,
I use gnugk with ActivateFailover=1 with full proxy mode (rtp proxy) and gentoo linux with fs.file-max=102024 . It crash if i have more then 130 calls because of not enough fd The gnugk is compiled with large_fdset=20480 With 90 calls i have :"lsof | grep gnugk | wc -l" 18494. As it describe in gnugk manual the large_fdset should be 10 (= 2 sockets for Q.931 + 2 sockets for H.245 + 6 sockets for RTP and other stuff) for each call, so for 130 calls i need 130*10=1300( supposed i have activated failover with 3 routes the fd should be at the most 1300*3-3900, but i have 20480 and at 90 calls it use 18494 file ) .
When it crash i have the follow error in logs:

So i read the source of pwlib : ../common/sockets.cxx, line 1405 and it's about file descriptor.
So the next step was to increase the number of fd for gnugk, some like 40k and the result was: all calls were falling with disconnect cause 3, disconnected by gnugk, and in logs : not enough memory(i have 1G ram memory),
2007/10/07 21:10:06.976 1 ProxyChannel.cxx(3771) RTP RTCP socket x.x.x.x:53547 not available - error 7/24: Cannot allocate memory
What can i do or where i'm wrong ?
