Informix - Problem description

Problem IT32162 Status: Closed

AN ONSTAT -G SES OR ONSTAT -G SQL CAN LOOP PRINTING MANY "(" CHARACTERS
RESULTING IN A LARGE ASSERTION FILE BEING CREATED

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
The instance that was running at the time was reporting some
memory corruption problems which resulted in an AF to be
generated.

While producing the "onstat -g ses 0" section of the AF, the
report ended up in a loop and printed many indented "("
characters resulting a very large file to be created which might
fill the file system.  You will see something like the following
towards the end of the session report ...

And now all you see are many indented ( characters being printed
and this also means that the other parts of the assert file are
not reported.
