Hi Monika, yes, this could help us reproduce the issue and test our fixes.
How can I get this package to you? My .gz package is still 360Mb which is bigger than what I'm allowed to attach here.
It's on its way.
Admin user name is testadmin, password is qwerty. It's set up for database user jeti/jeti, db jetijira, but you can change that as you like.
I've cut down anything that doesn't seem to affect the problem, and last thing I did before packing it up was ensuring that the problem persisted by commenting on issue SYM-15854 (see attached screenshots).
Anything else you need to know? Just ask.
Update: This hasn't re-occurred on our system in a year, so it might have resolved itself (by our Jira upgrade to Jira 7, any JETI upgrade, or something else, I don't know).
