Anybody has solution for the error in server task.
I reviewed the attached log but it didn't help me in finding out any pointer.
Could you please share step by step screenshot of the task you are trying to create with Orion log (\Program files\McAfee\ePO\Server\logs)?
There is a server task that allows you to purge various events. Modify it to include Purging Server Task Log and make the time to something like 60 days and then run it. I had a similar issue and that is what I did to fix the issue. I have this task set to run everyday so the log stays empty.
