Also, I came in this morning, and the server was pretty much dead. It
would respond to pings, and the radius (portmaster authentication
software) daemon was still authenticating users, but anything that
required the creation of a new process was dead. So I couldn't telnet
into the box, couldn't login to the console, sendmail wouldn't work, etc.,
etc.
Anyone seen this behavior before with 2.0.6?

Subject: Kernel Oops in 2.0.6
I've been having some problems with the stability of 2.0.6. We use Linux
here at CacheNET (a small ISP) for our server and programming terminals.
Linux 2.0 has been very unstable for us, usually dieing silently when
nobody is around to watch the machine. 1.2.13 was rock solid for us.
I've never done an Oops report before, so I'll give as much information as
possible.
The kernel was compiled with GCC-2.7.2 + binutils 2.6.0.14. I am using
libc 5.2.18.
The machine is a Pentium 100 with 32 megs RAM, 4 and 1 GB SCSI drives,
SCSI tape backup and SCSI CDROM drive. The machine has the buggy CMD640B,
but the floppy on this machine was not, and has not been used.
I finally got an Oops copied down...
