| |
Hey there,
I have a bunch of web servers all running RedHat 6.0 that use 2.2.10-13 kernels. The servers are a collection of PPro, PII, and PIII's with different motherboards, scsi, network and video cards. Since moving to 2.2.x kernels, these servers have not been very stable under load. Back with 2.0.x kernels, I would have 90+ days of uptime.
But after doing fresh installs of Redhat 6.0 and rebuilding the kernels, I only get uptimes of a week or less before the different boxes lock up solid. When one locks up, I don't see any Oops or kernel panics or anything else that might give a hint as to what happended.
About the only thing common between all of these servers is that they all run serial consoles with this line in lilo.conf append="console=tty0 console=ttyS1,19200n8" Now I haven't tested this extensively yet, but it appears that when I reverse the ordering or drop the serial consoles, the servers appear to be more stable.
Is this just a coincident or could there be a problem somewhere in the kernel that would cause the system to be less stable when a serial console is used as the default for /dev/console? Or am I just missing something else more obvious? I ran memtest on everything and they all come back error free, also all these boxes ran 2.0.x kernels without problems.
I'm just not sure what else to try, any suggestions? David
