TFS4JIRA Self-Hosted | The synchronization process stops running and you have to revisit TFS4JIRA configurator page to get it running again.

By default, an IIS application pool (or “AppPool”) recycles on a regular time interval of 1740 minutes or 29 hours.

Users may notice that after such recycle, sync does not run until TFS4JIRA configurator page is opened. Please follow the below 4 configuration corrections in order to minimize this situation.

WORKAROUND (optional when above failed)

That situation where Synchronizer stops processing after application pool recycle is the standard behavior of IIS 7.0, not an error or issue. The site only comes into memory on first access and that usually takes longer than subsequent access.

The solution or rather a workaround. is to create a scheduled task on event id 1033 with a simple command:

running from the SYSTEM account.

Please of course remember to enter your synchronizer address and port.
