Then you should have the debugging symbols in place, yes.

Doesn't matter.

Stopping multipathd isn't problematic.  It is only responsible for
periodically testing paths to pre-emptively fail non-active paths or
re-instate paths that has been failed by the kernel's dm-multipath layer.

If everything is running stable with all paths alive and well,
restarting multipathd is nothing to worry about.
