I have some machines that run customers cgi stuff.
These machines have started to hang and become unresponsive.
At first I thought it was a hardware issue, but I discovered in
a cyclades log the following stuff that got logged to the
console which explains the cause of the system hangs/failures.
vnode_pager_putpages: residual I/O 65536 at 347
vnode_pager_putpages: I/O error 28]
vnode_pager_putpages: residual I/O 65536 at 285]
Zillions of them.
The only way to recover the machine is to power cycle
From what I can tell from google etc.. and someone elses
experience it is probably the consequence of someone filling
up /var/tmp or something.
Should a non root user program be able to DOS
a machine like this? or What is the cause and/or fix for this?
thanx - steve
