Tomcat stopping related to Process Deadline Checker
Confluence User - 02 May, 2017
Hello, we have been having problems with tomcat stoppings with no apparent explanation. In the case that I copied below, there is a similar procedure to the query-response example of approvals via e-mail that is based on the expiration of a task. We do not run anything else or enter new information and in the log, in the middle of the night we see this:

We are currently working on a modification that does not rely on the loop for verification, but it is also an unexpected behavior that affects the application. We have not found much documentation on this. Do you think a fresh installation will help?
