Informix 9.40.FC2 Crash.
Hi all,
I work with Compaq Tru64 UNIX V5.1B (Rev. 2650) and IBM Informix Dynamic
Server Version 9.40.FC2X1
This is a part of af file generated from the crash:

Time of failure: Tue Jan 13 17:06:50 MET 2004
AF file: /u/tmp/af.4391799
Shared memory file: None
System Blocking: OFF
This a part of my onconfig
DUMPDIR /u/tmp # Preserve diagnostics in this directory
DUMPSHMEM 1 # Dump a copy of shared memory
DUMPGCORE 0 # Dump a core image using 'gcore'
DUMPCORE 0 # Dump a core image (Warning:this aborts
OnLine)
DUMPCNT 0 # Number of shared memory or gcore dumps for
# a single user's session
Last month I called tech support: I send them online.log onconfig and af
file, but they needed a dump of shared memory to solve the problem, so I
modified the onconfig (DUMPSHMEM 1 ) and restart Informix.
Now I count 5 crashes due to the same problem (btscanner I think).
I have some questions about these crashes that occour on my system:
- Has someone a similar problem?
- Why it doesn't create the dump of shared memory?
- Are there bugs with btscanner and 9.40.fc2?
Thanks in advance.
