Hi all,
Hope everyone is doing fine !
We are facing issue related to dispatcher cache invalidation.
Activation to publish servers is working perfectly fine. When we add /statfilelevel entry to dispatcher.any with any value (1 , 2 or 3) then dispatcher cache invalidation does not work. We can see ".stat" file timestamp changes but that also does not invalidate the dispatcher cache. When we remove /statfilelevel entry from dispatcher.any everything starts working fine.
Any reason why this is happening. Obviously we want to leverage /statfilelevel entry. Attaching dispatcher.any for your reference.
Please let me know if you have encountered similar issue.
Thanks in advance
