I've tried setting the following -
# closeDelayBatchLock = 60000; /* in ms */
# closeDelayExclusiveLock = 2000; /* in ms */
# closeDelayNoLock = 500; /* in ms */
closeDelayBatchLock = 0; /* in ms */
closeDelayExclusiveLock = 0; /* in ms */
closeDelayNoLock = 0; /* in ms */
which seemed to cure problem 1) and change problem 2) so that I only need a
1 second delay. But no delay between f90 commands will still fail. Not sure
what other side effects this will have. Have also tried nfs2 vs. nfs3 but
no change. -John
