Some problems in kernel 2.4.3
Hello.. All..
I upgraded the linux servers' kernel verison from 2.2.16 to 2.4.3 . when my linux kernel version was 2.2.16, there is no problem to work. but After upgrading, some critical problem is occured. Surely, kernel compile option and method has no problem. (H/W spec is P3 733 Dual, 512M RAM and SCSI)
(1) some process is not killed
I built kernel 2.4.3 in my linux server which works in php+mysql. But after a few days, I found that my mysql daemon was not work. (But mysql process is seen)
So I typed like this to kill the mysql process.
kill -9 pid or
killall -9 -ev mysqld/usr/local/mysql/bin/mysql.server stop
...... etc....
But I can't kill mysql process with any command. So I reboot the system.
(Unfortunately, this phenomenon is occured very often and
occured other linux servers that kernel is 2.4.3...)
Of cource, mysql process is just a sample
and other process(proftpd, sendmail, etc...)
is not killed either.
(2) Anyone (even root) can't access some directory.
A few days ago, I moved the special user's directory and typed "ls -la" to see the directory structure. but that command was not work and the process is stopped. --- keyboard is not work too.
(the process is not dead even would kill the process as root)
so other processes to access the directory were seen in the "ps aux" command. and the load average is so high(about 100) even all processes are killed except those undead processes.
and the load average can't down any more before reboot the system.
I think that these two problems are bug in the 2.4.3 .
Please give me some advice about these problems.
Thanks for your help.

I've been using 2.4.3 without any problems and I also use php, mysql, proftpd, apache, etc...
Are you sure you upgraded userland tools to the versions stated in the changes file?

From what you're saying it could be problems with your drive or drive
controller or something. Can't say until you provide more information. What hardware?
