Hi all,
Any ideas, why is this happening or how to debug this? After random time
(usually one to three days uptime) inode-sz reported by sar jumps way up its
normal level and <24 hours after this bug has happened server will crash.
Server used to work fine, but started to do this around beginning of June.

Disk activity stops in a very weird way:
I can ...
- create new files with commands like "echo test >test" and read
them.
- move around in directory structure.
- use "df" and such commands.
But ...
- all kind of syslog activity freezes, no new stuff to /var/log/, although all
the processes seem to run as usual.
- Apache seems to serve pages it already has been serving, but trying to surf
to the yet unvisited page, it will hang.
- restarting any service via "/etc/rc.d/init.d/x restart" fails (will
hang
when service is stopping).
Server is a dual P3 Xeon 700 MHz / 1 GB RAM / 200 GB (hardware) RAID-5 SCSI.
Distribution used is a fresh Red Hat 7.3 install, updated with up2date
whenever necessary.
Kernel version:
Linux xxx.xxxxxxxxx.xx 2.4.18-4smp #1 SMP Thu May 2 18:32:34 EDT 2002 i686
