CONTINUED: EWS Linux home directory service degraded

Update: Wednesday, October 16, 2013:

Linux lab computers were operating normally until about 4:30 p.m. today.  About 4:30 p.m. Engineering IT received reports that Linux lab computers and remote Linux server were experiencing problems.  Service was stabilized around 5:00 p.m. but problem resurfaced and continued through the evening.  Engineering IT staff have been engaged in monitoring and attempting to resolve the issue.

EWS Lab computers running Linux and the remote linux servers have been experiencing problems with accessing home directories intermittently this evening.  The symptoms include hung graphical Linux sessions, hangs on login, intermittent hangs when running graphical applications/login, apps stop working, or don't load, or the system just seems to freeze.  Sometimes they recover, most of the time that's short lived and then they hang again.  Engineering IT are investigating this problem, and will update this site with more information when available.
