[Serusers] fifo buffer

[Prajyot]

Hi Users,

I am pretty new to SER and currently administrating an SER server for our
company. The problem I am facing is the fifo buffer gets filled up pretty
fast when traffic is more on the network, sometimes the buffer (waiting
list) gets so high tht the ser deamon crashes and the server stops, I also
get he following errors when I just restart the server.

Oct 29 14:29:13 sip /usr/sbin/ser[13883]: authorize(): Invalid nonce value
received, very suspicious !
Oct 29 14:29:17 sip /usr/sbin/ser[13884]: authorize(): Invalid nonce value
received, very suspicious !

Also there is a lot of 401 (unauthorise) errors, 

The error which I got when the ser server crashed was;
Oct 28 10:05:35 sip /usr/sbin/ser[29943]: child process 29973 exited by a
signal 11
Oct 28 10:05:35 sip /usr/sbin/ser[29943]: core was not generated
Oct 28 10:05:35 sip /usr/sbin/ser[29943]: INFO: terminating due to SIGCHLD

I release signal 11 is a segmentation fault and the iptel web site refers it
happens due to a bug in the software (we have SER v 0.8.10),  Initially the
ser server was set up using an RPM, so please guide how can I reduced the
fifo buffered packets, will increasing number of ser childs would help???

Thanks in advance
