[SR-Users] kamctl fifo <command> not responding

[Daniel-Constantin Mierla]

Hello,

do you get anything in kamailio log messages when the fifo is not 
responding?

What version of kamailio do you have?

Removing and creating a new one will not help, since kamailio will not 
reopen, so practically will still use the old file descriptor.

Cheers,
Daniel
