[Asterisk-Users] Regular Crashes

[Zafer Khodr]

I have been experiencing a similar problem.

I have not yet been able to figure out what the exact problem is but I know
that the errors are inconsitant.

Sometimes nothing for 2 days and sometimes 5 times a day.

 

I thought about it a lot and I have found only one thing in common.

 

The area where my server is stored gets pretty stuffy, especially on a hot
day.

 

I occasionally turn on the aircon as I need to go in and do some work.

>From my best recollection the server has never crashed when the aircon has
been on.

This is my third day of testing my theory, and with the aircon controlling
the room tempreture to make sure it is always nice and cool in there I have
not seen any errors for 3 days (Keeping in mind that the day I decided to
try this theory by constantly keeping the room cool my server encountered
around 4 errors in just a few hours).

 

So to put in short I think but cant be sure that somehow when the room gets
too hot the server goes awol and somehow causes this error.

Don't ask me how or why. all I know is that now with controlled room temp I
have not had a problem.

 

Good Luck

I have just setup asterisk on a debian sarge box. I am running Asterisk
1.21 with AMP and chan_capi_cm 0.6.1  using a BT Speedway (AVM Fritz)
ISDN card, connected to a BT ISDN2e line. Currently we have 6 extensions
(SIP) configured all using CounterPath(Xten) eyebeam softphone.

After many hours of Googling I have finally got it all setup and
working. We can transfer calls internally and make and receive external
calls. Its all great except for stability issues!!

Essentially  every now and again, asterisk simply dies (2-3 times a
day). No warning, no error, just my console session outputs a
disconnected from console message.

Sometimes the crashes happen when you are on a call, other times when
there is no-one in the office.

The server is a brand new AMD 3400+ with 512Mb RAM. The other issue
experienced is occasional break up on inbound sound quality.

Below are traces of the last two crashes

Any Help much appreciated

Andrew Gough
