When you say existing mounts stop working, do you mean that data is no longer available on those existing mounts, or that new connections requiring new contexts via svcgssd stop working? Could you send a packet trace from the server after mounts stop working? (tcpdump -s 0 -w /tmp/x) Also, if it is enabled, could you get the output from sysRq-T? ------------------------------------------------------------------------- Using Tomcat but need to do more?
