Bug Description
Binary package hint: multipath-tools
SRU justification:
=====
Impact: stopping multipathd (i.e. to restart) can cause a segfault
How bug addressed: an upstream patch is cherrypicked which avoids dereferencing a backlog of syslog messages when it is empty.
Patch: See the debdiff in comment #8
Instructions: Start multipathd, then stop it, watch segfault.
Regression potential: If there were an error in the patch, then it should at worst fail to log backlogged syslog messages at shutdown.
=====
Sometimes multipathd segfault when i do /etc/init.
