Perl can do this is when you've run it out of file handles, then someone
tries to load a not-previously-loaded Perl module. The Perl interpreter
needs one more file handle to open the new module, but it can't get
another from the kernel, so it gives that message.
Generally this results from a bug in the code, typically one involving
an over-reliance on Perl's garbage collector. Perl will close opened
file handles for you eventually, but not as long as it thinks they're
still being used. If you have a long-running script, you need to be
careful about this if it also opens a lot of files, since the default FD
limit per process is 1024 on Linux.
You can monitor FD usage in a program with
ls /proc/`pidof my-program`/fd | wc -l
I don't know if you want to put "xymon_event" in for "my-program" or
something higher up, since I don't know anything about that or ClamAV.
Regardless, if you see that number climb continuously, then see the
problem happen shortly after the number crests 1000, you've confirmed my
guess.
