Hi Team,

Production author outage happened two days ago. We can see update_asset transaction took more time around 169 sec also the most time consuming 50.8%. We have noticed that around 50 assets were uploaded on that day. We are not able to identify the root cause for this outage. In order to prevent these outages in the future what precautions we need to take. It is an AEM assets application.

Take the thread dumps (at least 5) as suggested during the time the issue happens and run analysis on it using thread dump analyzers available [1].

50 assets should not cause an outage. There is probably something else that caused the outage. Analyze the following information:

- Log files

- Thread Dumps[1]

- Heap Dumps [2]

If you are not able to find anything, I would recommend logging a daycare ticket.

Scrape through logs for more information, probably Update asset workflow or xmp writeback could be the reason.
