[OpenSIPS-Users] Problem with mi_fifo replies

[Bogdan-Andrei Iancu]

Hi Brian,

Does opensipsctl through some error ? because I see opensips receives 
the command (via command FIFO), but it is not able to reply back because 
the reply fifo does not exists. The reply fifo is created by the 
application that fires the request, the opensipsctl in this case. So, 
either opensipsctl does not properly create the reply fifo, either it is 
created with wrong permissions (like if you run opensipsctl as root, the 
reply fifo will be created with root ownership and opensips, running as 
osuser, may not have permissions to write into the reply fifo. 
So, if there are no error, try to run opensipsctl as user osuser also.

Regards,
Bogdan
