Howdy! FreeBSD 4-10 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 it. 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 "The age of the Internet has a right to its own music." http://www.linuxsuite.org
