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

[Thomas Haeger]

Hi Scott,

thanks for your help. The frame errors which you got i don't got.
Yes this is a slow machine, but i greenly thought that * can handle about 30
calls on it without
problems....

Have you ever run 120 simultaneously calls on one machine ?
What does you mean with "How many instances are you running" ?


Best regards,

Thomas.

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
