We have some application connected to ASE 11.5.1 using jConnect40 JDBC
driver, on NT4 SP4.

The application crash (Dr Watson) sometimes, a few seconds after having
in the NT application event log the event :
Source : SYBPERF
event id : 12
type information
catgory : monitor
description : 7: [WELCOME] - NT Performance Monitor has started
monitoring SQL Server.

We see in the ASE configuration an option "SQL Perfmon integration" that
was set.
I expect that if we disable the option, the problem will not occur.

My question are :
-what is the trigger that start this monitoring ?
-why does it crash the application (ressource limitation,...) ?

(we have no error in the ASE error.log when the problem occurs)

Thanks for any responses.
