Good afternoon. Freeswitch info: Freeswitch version: Version 1.6.12 64bit O.S: Centos 7 Processor: Xeon Six Core RAM: 8GB Disk: SSD samsung 850 pro I've been facing a problem with freeswitch. When I generate many calls (around 300 calls), Freeswitch service stops receiving socket connection after this error: [ERR] mod_event_socket.c:3017 Error initilizing connection [CRIT] mod_event_socket.c:235 Stateful Listener 0 has expired [ERR] mod_event_socket.c:2975 Socket Error [Too many open files] I set the configuration below, but the problem persists and I have to restart the service to get it back up. ulimit -c unlimited # The maximum size of core files created. ulimit -d unlimited # The maximum size of a process's data segment. ulimit -f unlimited # The maximum size of files created by the shell (default option) ulimit -i unlimited # The maximum number of pending signals ulimit -n 999999 # The maximum number of open file descriptors. ulimit -q unlimited # The maximum POSIX message queue size ulimit -u unlimited # The maximum number of processes available to a single user. ulimit -v unlimited # The maximum amount of virtual memory available to the process. ulimit -x unlimited # ??? ulimit -s 240 # The maximum stack size ulimit -l unlimited # The maximum size that may be locked into memory. ulimit -a # All current limits are reported. I can't execute any freeswitch command, fs_cli -x "show calls", fs_cli -r, they all return that socket error. Thanks.
