asterisk users - Oct 2008 - Asterisk/Machine Hang after calling in/out ISDN

I am testing Asterisk 1.4.22, zaptel 1.4.10.1 and libpri 1.4.4 on RHEL5
on DELL PE2950 and using ISDN-10.
I thought about cutting over to production tonight when I noticed a
serious problem.

SIP calls are fine but if I dialed to outside (Dial(Zap/g1)) a few times
or someone called in a few times, Asterisk just froze (cannot enter
anything on the CLI console) and then even the machine had to be
rebooted.

I suspect there is a problem with zaptel.  
Is zaptel 1.4.10.1 a dodgy verions?
Any suggestion on how to debug this problem?

No message on the console of the machine?

This probably means one of two things:

1. Bad kernel-level deadlock (maybe caused by Zaptel)
2. If asterisk is running with -p: it might be in a 100% CPU loop.

if your ISDN card was installed new.. try disabling any built in PCI
interfaces.. that's what i see for now.. and let me know if it works.-- AHD

Yes, nothing at all.
The machine just froze and had to be rebooted.

I will upgrade zaptel to the latest version.

I just use whatever it is in /etc/init.d/asterisk.
I checked the file and it does not come with a -p option.

I checked /var/log/asterisk but there is nothing unusual I can see.

Any thoughts?
