There have been a number of fixes to the lrmd since v1.1.10. It is possible
a couple of them could result in crashes. Again, without a backtrace from
the lrmd core dump, it is difficult for me to advise whether or not your
specific issue has been fixed. Building from source could yield better results
for you. The pacemaker master branch is stable at the moment.
