Hello,<br>
<br>
what version are you using? Are you doing sql queries that return
large number of records (e.g., via sqlops)? Are you using any custom
module you developed?<br>
<br>
The crash was fixed in master branch, but somehow forgotten to be
backported -- it is now in branch 4.1.<br>
<br>
Cheers,<br>
Daniel<br>
