Hello all,
Recently we ported our code to latest lucee.
We use memcached for session management.
Since the upgrade, once in a while some clients ( not all) experience a 500 error.
The only way I could resolve the issue ( which I found by accident) is to go into Lucee Admin and edit Memcached and click on clear cache. The issue is by doing that, I am probably clearing everyone’s session cache to solve few client’s 500 issue. Anyone know why this is happening and how to solve this?
Greatly appreciate any help.
here is the stacktrace
