When I ran gcore on the pid, it produced a whole bunch of memory read errors
like this:
warning: Memory read

gcore is part of gdb:
Okay, I have this happening again on a couple servers right now, and am happy
to let it spin and dig more into it. I'm not at all experienced with stuff
like this though, so will need some explicit instruction on what to do beyond

Is there something more I can do to gather more information when this happens?
I'm not very familiar with strace, just ran it on the PID and saw the screen

I'm not very familiar with strace, just ran it on the PID and saw the screen
fill up with sched_yield() lines... This happens

It's x86_64, running Ubuntu 16.04; the latest package versions available from
Ubuntu repositories. They are vmWare ESX nodes with 16 CPU cores and 64GB of
memory

On a couple clusters that have been running for a little while (without

When I look at ps, I can see that these have something to do with pcsd:

On a couple clusters that have been running for a little while (without
fencing), I'm seeing runaway server.rb processes using 100% of a single CPU
core each.
When I look at ps, I can see that these have something to do with pcsd:
