When i call to asterisk , asterisk give me a CONGESTION status. When I check my log , it was given following warning : 

[Mar 17 13:33:03] WARNING[657] acl.c: Cannot create socket
[Mar 17 13:33:03] ERROR[657] rtp.c: Unable to allocate socket: Too many open files

[Mar 17 13:33:32] WARNING[657] channel.c: Channel allocation failed: Can't create alert pipe!
[Mar 17 13:33:32] WARNING[657] chan_sip.c: Unable to allocate AST channel structure for SIP channel
[Mar 17 13:33:32] NOTICE[657] chan_sip.c: Unable to create/find SIP channel for this INVITE

I have given high ulimit value but still problem arises. Can anyone know how this problem arises and how it could be stoped.

Just try below two lines in command line

sudo asterisk -cvvvvvvvvvvvvvvvvr

In asterisk CLI

ulimit descriptors 180839

1) check selinux/apparmor security settings

2) check limits for running proccess

Check the open FD limit for a given process in Linux

3) check system wide limits for user asterisk(not root).
