I left my Ubuntu Linux 8.04 Workstation logged in over the week-end and found the computer completely hung when I came in Monday morning. I assumed this was just due to our use of Kerberos authenticated NFS mounted home directories and rebooted the computer. It appeared to boot fine, but when I logged in I was given a blank screen. The log-in was successful, but no desktop appeared. After switching to the console, I saw that GDM had run krenew -t -- gnome-session, but gnome-session had not been executed. krenew was using 100% of the CPU and I could not kill it even using SIGKILL. I restarted gdm and tried to log in a second time with the same results. I then tried running krenew and krenew -t from the console as a normal user. Both commands succeeded with no error, but when I ran krenew -t -- ls, it hung with no output. Looking at the kernel logs, I found one relavent line:
[ 170.202812] afs_pag_wait() PAG throttling triggered, pid 7641... sleeping. sleepcnt 0 Pid 7641 is the initial krenew process which hung. After rebooting I had no trouble. -- Loren M.
