Problem with bad distribution

Moin!

I'm a happy user of inn since the 1.5 days and one of my recent newsserver
ran from Januar 99 till yesterday without any problem. It was our main
feeder that has up to 50Gb news throughput a day.

Innd now fails about two minutes after it start and I believe that this is
caused by bad article with a wrong distribution send by one of our peers.
I first believed that it was caused by the somewhat exotic cycbuff setup I
used (I use mirrored raw devicese on Solaris). But after I setup another
server with the recent snapshot relaeas of 2.2 on another solaris box I
encounterd the same problem. 

Innd dumps core and when I backtrace to it the output is:
Core was generated by /var/news/bin/innd -p4 -r'.
Program terminated with signal 11, Segmentation Fault.

I "fixed" the problem for now by disabling the output of the wrong
distribution to the logfile, I hope you can find a proper fix. You can
contact me if you need further help (i.e. access to our site).
