Workstations connect to the server via XDMCP for control of the local plant. In the past they ran two discrete Ubuntu servers, which used to run reliably for months at a time. Since the switch to the high availability cluster, they now find gdm will refuse to accept new logins after about 6 weeks of operation until the gdm service is restarted. The restart of gdm has the effect of booting off everyone currently logged in -- so for a few seconds, everyone loses control of the processing plant while people re-connect, every 6 weeks. The logs show the following: Sep 20 08:23:38 cgmv1 gdm-binary[31050]: CRITICAL: could not add display to access file: Too many open files Sep 20 08:23:38 cgmv1 gdm-binary[31050]: WARNING: Unable to set up access control for display 1691 Sep 20 08:23:38 cgmv1 gdm-binary[31050]: WARNING: GdmDisplay: display lasted 0.010690 seconds Doing a search, it would appear this is a file-handle leaking bug reported to Red Hat back in February 2010: https://bugzilla.redhat.com/show_bug.cgi?id=562143 Comment #2 of that bug has a patch that allegedly fixes the problem. I have hand-applied the patch against the latest stable source package of gdm (2.30.2.is.2.30.0), which I have attached here and am in the process of testing.
