Hi all
I experienced a problem more than once now. It crashes my box. And I
belive it's the isdn-code.
So here is my config: Redhat 5.2, plain kernel 2.2.5 patched with the
isdn-tgz from suse. (same some weeks ago with 2.2.3).
The box is used for sending Messages to Cellphones using an old AVM
Fritz ISA-Card. After some days (once it made it 2 weeks) the system
just stops working :(
The only thing I find is this from the logfile (and on console):

and then silence.
yaps is the programme that sends the messages. It uses ttyI4. Since
often the dest. number is busy, more than one yaps tries to use ttyI4
simultaneously, but all but one are blocked (this is how it should be, I
think). Perhaps this leads to the problems?
Could anyone of you solve this ? ;-)
