Invalid value for 'jira.index.readerpooling'

[Pedro Santos]

I've installed JIRA 7.6.9 and the logs are getting flooded by the error below:

[c.a.j.config.properties.PropertiesUtil] Invalid value for 'jira.index.readerpooling'. Defaulting to true. IllegalArgumentException: null

This occurs with practically every action- create, comment, assign...etc

Does anyone know what is this 'jira.index.readerpooling'? could not find any info regarding this.

Tried to clean the cache and did a full reindex but did not solve it

Thanks

Hi Pedro, 

Can you take a look and see whether you've configured this value to false, or any other value other than true, under JIRA Home Directory/jira-config.properties

There were some updates to the way that Jira handles reindexing in https://jira.atlassian.com/browse/JRASERVER-67125 which may be related. 

Jira indexing happens whenever an issue is created or modified in anyway, so that explains why you're seeing this so option.  The reindex event would not modify the configuration, just regenerate the indexes themselves. 

If you haven't manual overwritten the default value of this property then perhaps another add-on or customization is causing it. 

Hopefully this points you in the right direction. 

Cheers, 

Keri

Hi Keri,
I did not configured this, as I have no idea what this can be.

On the jira-config.properties file there's no info regarding index.readerpooling.

Do you know what is this for? or where can I find it?
Searched on jira system info, on most of the config files and got the same results as with google: Nothing

Can this be stored just in the db?

Thanks
