I think you've already reported the issue.

It's actually considered to be a feature that the library warns
you when it couldn't run the signal handler (or similar) in a
timely fashion. Now, what's the cause is really up to the
administrator to find out and take a look at how computing
resources on nodes are used. Typically it's a severe load caused
by backup or some other I/O intensive task. There's probably not
much more one can do about it.
