Sure, but I think for engineering to make progress on this bug, they
are going to want a crash dump. If you can enable crash dumps and
panic on lbug (and if HA, increase dead timeout so it can complete the
dump before being shot in the head) it would provide more info for the
bug report.
That being said, there are quite a few other bugs that have been fixed
since 1.8.0, so you really should upgrade ASAP to 1.8.4.
