Thanks to all respondents.
I took a complete backup of my system and applied the 2.6 Recommended Patch
cluster. I held my breath for full 20-25 minutes when the patch cluster was
applied and rebooted the machine. The system is stable now (atleast for the last
two days).
Thanks again

Hi all,
Thanks for your inputs.
Thanks to
Kevin Buterbaugh
Merell Vince
Jamie A Lawrence
Rakesh
Reggie Stuart
Most of them suggested to upgrade patches to the latest level.
I took a full backup of my filesystems and I downloaded the 2.6 Recommended
patch cluster from sun.
Before applying this patch cluster, as a precautionary measure, I want to know
whether any body has ever faced any problem with this patch cluster.
thanks in advance. I will summarize.
regards
venkat

Subject: E3500 Reboots
Hi Sysadmins,
I have a E3500 (dual processor, 256MB RAM, Solaris 2.6 patch 105580-01) running
quite a lot of software (db2, oracle, mqseries, apache,samba, mastercraft
etc..). It is serving about 30 - 40 users. This machine primarily used for
development.(C++) and database load is not much . nor it is used as a web
server. The machine has plenty of CPU time (avg idle time is 70 -80%) and
memory constraints are not much..(it has about 900 pages of freemem at peak).
>From yesterday onwards, it is rebooting at random intervals. (till now two
times). I traced a bit and found that it was due to a BAD TRAP exception. The
following message is logged on system console (but it is not there in syslog).

Apart from this, users are running SWIFT NET LINK software which is used to
connect to SWIFT Network. Atpresent SWIFT net is not active and we are using
Loopback and the Swift net TIME Service complains frequently about the
unavailabilty of SWIFT NET which normal when we use loopback.
I am seeking the following info.
1. Is there anyway to find out the process name for the pid 20549 after
reboot? (is db2bp the process causing the failure? secondline of
dump). it is nothing but a db2 interactive session.
2. Is there any patch suggested for this kinda problem
3. Your suggestions
Thanks in Advance . I will summarise as always.

venkat
