Hi All,

Thanks for all of your response.
We have configured cimserver "forceProviderProcesses=false", so that all the provider processes will be in the same context.
Now, we run "Valgrind" for cimserver process. And then, we have generated one event for our provider and stop the cimserver process after that.

Then from "Valgrind" memory leak report, we can see many definitely lost memory issue are coming from Pegasus. Please check the attached file for details of it. Is this a known issue?

Please give your valuable input. Thanks in advance.

Regards,
Pialy

Is the leak seen in a particular cimprovagt or for all the provider processes?
If It is seen in some particular agent processes, Then most probably it is leak in the corresponding provider.
See if running under a memory debugger helps for that particular agt processes.

Hi,

We are seeing some memory leak in cimprovagt process. We are running open Pegasus, cimserver in a windows 64 bit OS. Our provider is running on cimserver.
After few days long run we can see, memory usages is increased. I have searched in internet and find out same kind of problem is mentioned by others also. So, just wanted to know, is this a known issue in Pegasus? If not, then we will come to know that, issue is coming from our provider.

Your valuable input will be very helpful for us to analyze the issue.

Thanks & Regards,
Pialy
