[comp.os.vms] CPU intensive bug in database package "SIR"

A brief warning of interest to VMS users of the Database package SIR. 

Seems there is a bug in SIR V2.2 whereby DECNET jobs crap out when
using interactve SCHEMA and "SAVE". This happens when running VIA decnet
to the same machine (is on machine xxx typing "SET HOST XXX"). As
near as I can tell the parent waits for the child to terminate and the
child cannot tell who the parent is, and the resulting message craps out
the decnet link.

I hate to bother the net with this info, but seems that even after the
DECNET connection dies a child sub-process continues to run in an
infinite cpu-intensive loop!  SIR users should be warned that if a
SIR/SCHEMA job terminates abnormally they should make sure it's
children have stopped. This happened to me, and there was no message
which implied the job did not trap the erro normally, but the next day
someone notice my child was STILL active and had consumed 11 hours of
CPU time in 14 hours wall time because of this bug!

Regardless, the SIR 2.2 is a >>>VERY<<< hardy version.  Besides, life
would be mundane without the un-expected,  eh?
