Intermittent problems with Grex internal Ethernet switch

Grex's internal GigE switch is intermittently unavailable due to what appears to be firmware issues. This affects availability of internal Grex services such as Torque and Moab servers, LDAP authentification and such. Running and queued jobs and data should  not be affected, but logins to the system and commands like showq, qstat and qsub might intermittently fail. We are working on resolving the issue.
