Details:
The dpm-xrootd sites are running a cmsd with XrdPss configured like this:
if exec cmsd
all.role server
ofs.osslib libXrdPss.so
pss.origin localhost:$(xrootfedlport)
all.manager $(xrootfedcmsdmanager)
fi
(no N2N or Oss plugins in the process, whole config file available if it
helps).
There have seen some crashes of the cmsd processes, on at least one occasion
at three different sites but related in time:

I will try to get a core dump and in the mean time also do some investigation
to get more information, if possible.
