report from user:
Did some extensive testing… problem appears to be with the sybase userid. I connected via SQL Programmer to DSN=MY_SERVER;SRVR=MY_SERVER;DB=MY_DB;UID=XXXXXX;PASSWORD=XXXXXX; then tried to run
sp_AddEntry 5464,"Jason Test","12345","localhost","asdfasdf","20-Sep-2005 12:32:43"
it failed… no errors from Sybase.
Further analysis revealed that this ‘hanging’ was only occuring with non-sa users. This indicated that either permissions issues or auditing was suspect. I was able to determine that the database was most likely not the culprit by running dbcc’s on the user database with no errors reported.
I ran our new script reorg on the database which rebuilt all the indexes (or ran reorg rebuild/compact, etc). Curiously, the script hung on certain tables that also hung while running the stored procedure (above). No blocking spids were found but the locks were in shared and/or exclusive intent – meaning that we were waiting for some resource (in memory) to be freed. I told ASE to produce the stacktrace, the PSS memory structure and other items that allowed me to correlate that a lock on one of the audit memory structures was preventing ASE from performing the tasks.
From this information, I was able to identify the Sybase ASE bug (CR 428591) that is scheduled to be fixed in v12.5.4 esd 3 (Dec 2006).
When I opened a case with Sybase, the TSE said:
I have picked up your case involving suspicion of Sybase CR 428591. I have associated your case with that CR (on speculation at this point), although certainly your stack trace looks similar to that indicated in the CR. However, this CR has been closed without any problem identification or resolution. It was simply a consultation CR with Engineering. As such, we aren’t likely to see any activity on the CR. If you want further action taken, since we cannot confirm any bug here, we will need to get a memory dump for the situation and go to Engineering in the usual manner.
I’ve asked the TSE to confirm his statements as other Sybase cases state that the fix will be in v12.5.4 esd 3.
As far as the memdump is concerned, the sybase server is running at the maximum amount of memory that is allowed for a 32bit server. This means that there isn’t enough free space to attach sybmon to the shared memory segment.
UPDATE:
I was able to confirm with Sybase ASE engineering that Sybase ASE bug 428591 will be fixed in 12.5.4 esd 3 which is slated to be released in late December / early January.
