[GE users] Scheduler stops transferring queued jobs after GDI error

Thank you for your reply and help. We're a bit stick with this problem
being that the hardware, OS, grid configuration haven't been modified for
over 6 months other than adding a few submit hosts with the "qconf -as
Our grid uses local spool directories (execution hosts storing their logs on
their own hard drives).
On the qmaster machine "df -h" dislays:
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 65G 6.0G 56G 10% /
11G 3.1G 7.4G 30% /rmt/sge61
udev 2.0G 76K 2.0G 1% /dev
"/home" isn't mounted or used by the qmaster machine.
The sgeadmin home directory is stored on the /rmt/sge61 remote file system
(a NetApp NAS device) mounted over NFS.
"/tmp", "/var", etc all sit on the "/" local volume and there is 56G free.
On Friday afternoon we upgraded our grid from 6.1u3 to 6.1u6 in case this
may resolve our problem. Unfortunately the problem still came back,
although not for a few days (before it was hanging after only a few hours).
You mention waiting for 6.2u5. Is there a reason why we should not use
6.2u4 and wait for 6.2u5?

are the spool directories local or on the file server?

Where: in /tmp, /var? No disk quota in place in /home?

I would wait for the 6.2u5 binaries being available. Although I can't
guarantee, that it will solve your issue.
