> multipathd[7165]: segfault at 000000000000000a rip 00002aaaaaf51a3d rsp 00007fff03b50090 error 4 Can you run multipathd as so: multipathd -v9 -d And provide the -200 lines output from the segfault output? You might need to edit the /etc/init.d/multipathd to have this work and pipe the output to a log file or so.
