The default FD_SETSIZE on Windows is 64 - this implies a single call signal handler cannot handle more than 64 sockets. Try to increase CallSignalHandlerNumber to 10 or 20, for example. ----- Original Message ----- From: "Hao Li (V)" <manager@xxxxxxxxxxxxx> Sent: Friday, August 20, 2004 8:11 AM Thanks Michal However, after I changed callsignalhandlernumber=2, the gk crashed after reaching 128 concurrect calls, which never happened before. i restarted the gk, and it crashed again at that point. Does this mean, i have to recompile everything first before i can increase the number to 2? it's not related to acct/radius/sql etc, c/z they were not used in this case. Would Linux version of 2.0.8 work better with less such call limits problem?
