Having insufficient max_fsm_relations causes severe problems, so don't
if you can avoid it. I would certainly recommend increasing it.
Note that increasing max_fsm_relations requires that you have a large
enough shared memory allowance in the operating system; if you're too
close to the limit and try to restart with the increased setting, the
service may fail to start. However, unless you're on something weird
that requires recompiling the kernel to update that limit, it should be
fairly simple to update it.
