[Serusers] Segmentation fault-fifo_server fgets failed: Illegal seek

[Ashutosh Kumar]

Hi ,
   I am getting a segmentation fault when my sip server runs. It happens
mostly when a client tries to call another client phone.
I think that this has got something to do with ser_fifo file permissions.
For that reason, the relevant code from my ser.cfg file is as belows;
---------------
 fifo="/tmp/ser_fifo"
 fifo_mode=0666
---------------


I am running SER-0.8.14.The debug trace is as produced below:
