To add a little (hopefully)...
If multipathd is dieing it is better to determine why it is dieing.
Running multipathd in foreground mode with verbosity may provide info.
"/sbin/multipathd -d -v4"
If the issue is multipathd causing a segfault you would need to build a
non-strip version and then use ulimit -c unlimited to allow creation of a
core file.
You could then use gdb post getting a segfault to run "bt full" on the
core file to hopefully determine the area of the problem.
