=============================

It has crashed 7 times since yesterday with the same af file and 6 times it was not vp: 1.
so informix kept running.

the session which was running last is:

/opt/informix/bin/onstat -g sql 53:

The program with that SQL code has not changed in months.
from the af file does it mean that the crash is occuring after
a seesion terminates.

TIA.
