[ROOT] Using root with OpenMOSIX

Hi folks,

	I'm running ROOT on a 5 node redhat-7.3 cluster.  We have
installed an OpenMOSIX kernel on each of the machines,  allowing
transparent clustering across all 5 machines.  The makers of OpenMOSIX
call it "fork and forget",  and for many applications we run,  including
large geant applications,  it runs fine --  big jobs automatically migrate
around the cluster to the least loaded machine.  Unfortunately,  every
time mosix tries to send a root application to another machine,  it
segmentation faults.  If the job is locked onto one node,  even a node
seperate from the home node,  the job runs fine.

	Does anyone have any experience using root with MOSIX or
OpenMOSIX?  Or are there any obvious reasons for this behaviour?  Any help
will be greatly appreciated.

	sam waldman
