Memory Dump not properly triggerred

For one of the agent in production DT 6.1 version, memory dump was triggered due to GC but description shows as "A memory snapshot has been triggered but a problem occurred while creating it.".

On checking logs, we could find the below, please advise the reason for this issue.

Based on the states in the logs, I think there may be a problem with post-processing. I'd recommend turning off 'Automatically post-process memory snapshot' under 'Options' (refer to screenshot attached), and try and take the dump again. If the issue persists, I'd say open a support ticket.

Hi Kayan,

Thanks for your reply!!

It seems the dump was generated when Application Process Out-of-Memory incident was triggered for the agent based on the settings in the Agent group. In this case, how we can disable the Automatical Post-process options.
