it's the client (similar to two-task, but just single-task)

         single-task message
When running single task, this event indicates that the session waits for the client side of the executable. Wait Time: Total elapsed time that this session spent in the user application.

Hello list,
I'm observing quite a lot of similiar entries in a 10046 (level 8) trace
file
created on a 8.1.7.4 running under AIX:
...

Elapsed times include waiting on following events:
 Event waited on                             Times   Max. Wait  Total

There is one primary key index, two other indexes (not unique)
and a context index on the column verg_bem.

Are there any changes to find out what is causing the system to spend 6
seconds in
the single-task message?
