Hi Mahmoud:

I will start checking the OLDsyslog.log file under /var/adm/syslog to see if you can find any errors.

There is many problem.
First check disk space.
#bdf
is there 100% used fs ?
Use top for memory usege
#top
is there free memory ?

Use glans to see is there some kernel parameter that is out of range !

For more information about error :

#dmesg
/look end of raport/

#vi /var/adm/syslog/syslog.log
#vi /etc/rc.log

Use
#stm (log tool) and check for
memory problem !!!!
Also if you have GSP
read the system log
GSP > SL

Have nice day

Also find core file and investigate some time


find / -name core

use command :file and strings

#file /xx/xx/core
#strings /xx/xx/core |more

for extend debuging use gdb

Hi

I suspect one of the file system is almost full.

If the filesystem are full then even u'll see some junk message on screen; but check syslog file also.
Thanks

Mahmoud --

More then likely, you were out of swap space.

This could be because you need to configure more swap space in general on the server or because one particular application started growing very large.

To be proactive, you could check your swap versus your memory and make sure you have 2x memory worth of swap (i.e. if you have 1 GB of memory then at least 2 GB of swap).

In the future if you run into the problem, instead of power cycling the box, capture a crash dump by doing a "TOC" of the box.
