issuefunction in expression continually running

[Deleted user]

After running a query including the following query

issuefunction in expression("", "assignee != reporter")

The query was started at 15:00.  Completed in about 30s but the following threads didn't complete until around 16 minutes later.  Actually I was able to run the same query again, which compounded the issue.  (one of our users in production did this 12 times! which caused JIRA to become unstable for nearly 30 min)

The thread takes a long time to stop (even after the query has returned it's results) and the following is posted repeatedly to the "atlassian-jira-slow-queries.log"

Well, this term (issuefunction in expression("", "assignee != reporter")) will be evaluated against all issues - that is why it is slow. You should always add a subquery to it:

issuefunction in expression("Project =ABC", "assignee != reporter")

Then it will evaluate the expression "assignee != reporter" it only against those issue found in the subquery. This should speed up your query.

BTW: I think this is a scriptrunner JQL function (not jtricks)
