Recurring error in Confluence logs

[Jeramy]

This morning our Confluence instance crash and while it was restarting, I started looking at the logs and discovered this error message 28 times.

2023-09-08 18:53:44,817 ERROR [http-nio-8090-exec-925] [[Standalone].[localhost].[/].[action]] log Servlet.service() for servlet [action] in context with path [] threw exception

I've done some research, but I cannot seem to find a solution or a reason why it occurs. 

Any suggestions?

Thank you.

@Jeramy Have you cleared the plugin/app cache?  You can also try restarting after you put it in safe mode to see if the issue still exists.

@Brant Schroeder - I have not tried clearing the cache files yet. Unfortunately, I still see this error after restarting the Confluence service. 

I will try that to see if it fixes the issue. 

Thank you.

@Jeramy did that resolve the issue?

[Jeramy]

@Brant Schroeder - I will have to doublecheck. I lost track of time and moved onto different things. Thanks for checking up. :)
