memory leak in active rma agent?

losisoft · Post by **losisoft** » Sun Jun 15, 2008 5:57 pm

Hi,

I have a couple rma agents, which look's like they are leaking memory:

The interesting number is the Private bytes. 1.7gb.

Agent is version 3.19beta

Any idea, how to look, what is leaking inside the agent?

Its not that easy.
Could you please provide more information?
- what kind of tests/actions are performed by this agent?
- do you use ODBC test method? If yes, what ODBC driver do you use?
- do you have installed some antivirus monitors, personal firewall, content monitoring software? Non stanard winsock components?
Could you try to setup Passive RMA on the same system instead of Active RMA?

Regards
Alex

I know.

- what kind of tests/actions are performed by this agent?
CPU Usage, UNC availib/free space, calling external vbscipts, shell scripts, generic performance counter (network card Bytes Total/sec), process counting, service test, URL tests, and ODBC.

- do you use ODBC test method? If yes, what ODBC driver do you use?
Yes, we use Oracle client for ODBC, version: 10.2.0.1.0

- do you have installed some antivirus monitors, personal firewall, content monitoring software? Non stanard winsock components?
Symantec antivirus.

Could you try to setup Passive RMA on the same system instead of Active RMA?
Will try.

Could you please try to disable ODBC test? If this does not help, try to disable antivirus. If this does not help either, try Passive RMA.

Hi,

I have moved the ODBC test to a passive agent.
And now I can see high memory usage with that agent as well.
So it looks like the ODBC tests are causing the memory leak with both agent. (active/passive)

We will recheck our code however I would say "it looks like Oracle ODBC driver causing memory leakage problem". ODBC drivers often have such and other problems

BTW: I cannot find version 10.2.0.1.0 on www.oracle.com. Oracle offers 10.2.0.2.0 and 10.2.0.3.0 versions.
Could you try to install up-to-date driver?

Alex
