| |
I sent this previously, but I don't think it made it to the list, since I sent it from the 'root' account. Oops. I hate it when I get my VCs mixed up.
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?

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... invalid operand: 0000 CPU: 0 EIP: 0010:[<011a3f0a>] EFLAGS: 00010606 eax: 011a3000 ebx: 01e82cc0 ecx: 01e82cc0 edx: 01e82cc0 esi: 000004d9 edi: 00010000 ebp: 008dc2dc esp: 00282ea8 ds: 0018 es: 0018 fs: 002b gs: 002b ss: 0018 Process pine (pid: 6898, process nr: 63, stackpage=00282000) Stack: 01e82cc0 00000000 00017981 00157e69 01e82cc0 00282f04 000005e5 00000003 008dc2dc 00000400 00010000 00000010 00000008 00000100 0012485e 008dc2dc 000005e5 0020a80c 008dc2dc 008dc2dc 00000000 0064f000 00017a5a 008dc2dc Call Trace: [<00157e69>] [<0012485e>] [<0011b863>] [<0011b964>] [<00179000>] [<00119017>] [<0011b734>] [<0010fc0f>] [<0010fad0>] [<0010a5db>] Code: c7 31 b9 b4 e4 31 74 c6 90 31 00 00 00 00 c7 00 01 00 02 00
