Error while resetting searcher: ISSUE message: this IndexReader is closed

[Edouard Dorcier]

Hi I got this error in my JIRA instance. Then CPU usage got to 100% and I had to reboot the instance. After this no problem but I would like to know if there are some reason to this error (did not find something after 6.3.8 version).

Current instance version is 7.1.2.

Here is the stacktrace :

org.apache.lucene.store.AlreadyClosedException: this IndexReader is closed

I think that one is too old, and related to the lock file and descriptor
