6027-761 [W] Attention: excessive timer drift between node and node (number over number sec).
Explanation
GPFS™ has detected
an unusually large difference in the rate of clock ticks (as returned
by the times() system call) between two
nodes. Another node's TOD clock and tick rate changed dramatically
relative to this node's TOD clock and tick rate.
User response
Check error log for hardware or device driver problems
that might cause timer interrupts to be lost or a recent large adjustment
made to the TOD clock.
