distributedLock message -- okay, or?

Implemented some caching with a redis/valkey cache, and I get this message in the log seemingly every time distributedLock() {} is used:

Could not release the lock [lockName], as the lock was not found, maybe it had already expired

Should this worry me at all?

Windows Server environment, running Lucee 5.4.8.2, Tomcat, Java 11

thanks!
