yesterday I changed my network setup at home. My Ethernet<->ISDN
router (Debian Linux 1.3) changed its IP, which meant that NFS
UDP-requests from an UDB on the ethernet where routed from ethernet
through ISDN to the default router. Of course, there wasn't any
machine to reply, and the retries blocked the ISDN link. I took the
ISDN link down, at which point the system about froze and gave me
heaps of the following messages:
Aug 10 14:50:06 mpih-hr kernel: Ouch, kerneld:msgsnd buffers full!
Aug 10 14:50:06 mpih-hr last message repeated 3 times
Aug 10 14:50:06 mpih-hr kernel: Ou:msgsnd buffers full!
Aug 10 14:50:06 mpih-hr kernel: Ouch, kerneld:msgsnd buffers full!
I suspect this was some kind of request-route message from the
kernel, which shouldn't really tie up the system!?
Cheers,
Hein
