[Asterisk-Users] PRI/E1: machine freeze/dies after a few calls

[CW_ASN]

I'm running an E100P (only 1 E1) in PIII 850, the last Friday I was sent 30
simultaneous calls, 5 seconds each call, using mysql to store cdrs. These
calls was generated by an Ameritec AM2, and routed thru our Siemens EWSD.
The vmstat shows that CPU was near to 20% idle with 30 ISDN Setups incoming.

PII 400? E400P? Man, you gonna fry your CPU...

Regards,

Gus

Hi Thomas-

I didn't look closely at your shell script, but I wrote something similar in
Perl (and used shell to start each instance of it).  I had a few problems
too with a similar setup (although no machine lockups)

*  You are running quite a slow machine to run this script on many lines at
once - I found that I needed a P4, 2.4GHz to keep up with 120 channels
simultaneously (I had one system to send and one to receive, and very short
calls - 3 seconds).  How many instances are you running?  Are you doing
mySQL call logging?

*  I found that I could only initiate about 18 calls at exactly the same
moment without getting failed outbound call errors from asterisk, so I ended
up staggering the start times a little.

*  With lots of new calls, I had tons of framing errors on the receiving end
(and occasional D channel restarts) when routing calls through my DMS100
switch - do you have problems like this?  I think this problem is specific
to the Nortel switch however.

Suggest starting with -vvvvc and routing all output to a log file...??

regards
Scott
