We need to figure out why the helper is exiting. If there are no error
messages in cache.log, then your system log may have additional
information such as the process signal that killed the helper. If it was
a crash, then your core dump directory should have the corresponding
core dump (make sure you enable core dumps!) that you can examine with gdb.

If you can reproduce helper crash while it has gdb attached, please post
the stack trace.

Sure, it may have. Most likely, the changes are not tested in an
environment matching yours, and the bug may be environment-driven.

If you get more details such as a backtrace, please consider filing a
bug report with all the details.

Thank you,
