On some Fuji patches, Service Catalog pages cause the semaphores to hang. This is caused by the cache running out of memory because items are being cached multiple times, whether or not they were already there.

Fuji Patch 3 up to Fuji Patch 8 instances may be affected. This issue can occur with just two users and a single item if both try to access the functionality at the exact same time. The majority of customers on the affected versions do not experience this issue as the issue is of concurrency where both the access must happen at exactly same time.

Steps to Reproduce

There are no clear steps to reproduce. This issue is more dependent on running out of memory than any particular process.


The fix is within the ServiceNow code base therefore a workaround is not possible. If you are experiencing this issue, contact ServiceNow Customer Support and request an upgrade to the latest Eureka Patch where this issue is resolved.

A temporary workaround is a cache flush, as the cache empties and builds up again as you browse the catalog.
