We are using version 3.9.1 now and we see plenty of the logs like
`stream-thread [service-e7c3de52-cf29-49c3-8f9d-1eea119ea532-StreamThread-1]
Encountered lock exception. Reattempting locking the state in the next
iteration.`
with the following stacktrace
`org.apache.kafka.streams.errors.LockException: stream-thread
[service-e7c3de52-cf29-49c3-8f9d-1eea119ea532-StreamThread-1] task [1_42]
Failed to lock the state directory for task 1_42

which is kind of fine I assume also given the log level INFO
But they are eventually followed by an ERROR like
`stream-thread [service-e7c3de52-cf29-49c3-8f9d-1eea119ea532-StreamThread-1]
standby-task [1_42] Failed to acquire lock while closing the state store for
STANDBY task 1_42`
Are we missing some other fix or is there smth wrong with the config on our
side?
