Description of problem:
System after 2-4 day may fully freeze. At critical moment loading not to high.
Only reset switch can help. If there are messages on console, i am don't know,
this system is at ISP, his support don't be able to read from console -((
Intels ISC/BMC/IPMI managment, can't to help, nothing in them. I can see only
voltage and temperature OK.
There are no kernel messages in file /var/log/messages, only aplication
sendmail, named etc.
Hardware is Intel SGH2 2xXeon 2Gzh/2Gb ECC RAM/ Raid Mylex AcceleRAID 170 64 mb RAM.
LAN driver is Intel e100.
Now kernel 2.4.18-24.8.0custom but, all previus kernels have same symptom.
May be where is some kind of DDOS attack ?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.Wait some time(2-4 days)
- could be a hardware problem? does the system pass hardware test like memtest86
( http://www.memtest86.com ), burncpu ( http://users.ev1.net/~redelm/ ) .... ?
- you try to patch the machine BIOS
- you try to patch the Mylex RAID bios
Test 4 x burnP6 is running one hour, nothing.
Processor 1 Temp | ok | 42.00 | Celsius
Processor 2 Temp | ok | 42.00 | Celsius
All others test and suggestions require phisical access to console. I can't do it.
Thanks, may be we make a decision to exchange server to new.
