[Asterisk-Users] chan_zap graceful failure

[Jeb Campbell]

I was wondering if anyone is working on graceful failure for chan_zap?

Let me explain the situation.  We are using a T100P and TDM400P (4 FXS 
for fax).  There was a major power outage and asterisk went down after 
the UPS (not a graceful shutdown -- my fault, no apcupsd running).

As soon as power came back, the server started.  However when it loaded 
wcfxs, port 3 on the card failed the tests (I assume from the module not 
being unloaded before power off).  Because this one port failed the 
test, chan_zap failed to load and asterisk will not start.

An unload and load of modules would not fix it.  I had to unload and 
restart (a clean restart).

While the unclean shutdown can be controlled in the future, I have had 
ports go bad and when they do asterisk will not start until the 
offending lines are removed from zapata.conf.  This is not a very 
resilient solution (especially if you are not on site).  I would much 
prefer for asterisk to keep running with what it has got.

I will be looking into the code (and this might be fixed in cvs-head), 
but I would like to start a discussion on this first.

Thanks,

Jeb
