RHEL 5 machine hangs
 
helo

I am having difficulties in figuring out what is happening to my system...the system was working fine till last sunday...on sunday when i tried to SSH using putty i could not and when I went into the server room it was stuck...so i had to restart from the power button...it was working fine. the last time i checked was after 8 hours...so i thought it was ok now...but in morning again the same problem... for the last 3 days...any idea?

Share the log files for better clearance (messages and dmesg). If any recent changes happened, post that also.

Well, you're getting slaughtered by "snmpd[3490]: Connection from UDP: [192.168.1.1]:62426" type msgs, probably filling your disk up.
I'd start with finding out what that is caused by and fixing it.

nailsd-s4=> Check the syslog and message log.
=> check the memory and I/O ,command is "sar -B"

2 Question--
(1) What is the memory size and how many CPU
(2) Have you upgraded the kernel few days back or change the kernel.
