you might help you out yourself by finding pending messages to this node
so check on mmfsadm dump tscomm ... output on that node
if you find pending messages to a specific node.. .go on that node and debug further..
if it is not an important node.. you might solve your situation by mmshutdown/mmstartup the demon
but as said before... I recommend to open a PMR and get help from the support team ..

Subject: [gpfsug-discuss] GPFS long waiter
Sent by: [email protected]
Hello all
I’m facing long waiter issue and I could not find any way to clear it, I can see all filesystems are responsive and look normal but I can not perform any GPFS commands like mmdf or adding or removing any vdisk, could you please advise how to show more details about this waiter and which pool it is talking about… and any workaround to clear it.
