I have what appears to be a bug new to news 2.11 patch level 14 that is
causing havoc on my (SysV 2.2 -286 Microport) system. This isnt
happening on each news batch, but is has happened with several...
The scenario is this:
1) uucico starts uuxqt to ``rnews'' a batch of arriving compressed
news.
2) rnews starts ``compress -d'' to uncompress the news.
3) rnews starts another ``rnews'' for some reason, probably to
read the uncompressed news input.
4) the new rnews reads through the batch and works fine until
(I presume) it gets to the end of the batch, and then it decides
that the `inbound news is garbled' and dies.
5) the newest rnews process stays in <defunct> state. Nothing
else happens.
6) These process chains stack up over time, a new chain being created
each time uucico runs, eventually crasing the system due to
insufficient swap space.
I havnt had this problem before patch level 14. What gives???????????
