Hello sunners!
My biggest genuine thanks to the following managers who sent me points of
view to go:
Eugene Kramer <eugene@uniteq.com>
Gert Marais <maraisg@saps.org.za>
Denvers, Simon C <DenveSC@europe.stortek.com>
We installed a set of patches for Oracle 7.3.4. And looks like it solved
the problem, as error messages disappeared. In any case installing latest
patches for Solaris 2.5.1 (cluster of recommended patches) would come in
handy as well. Be sure, the system has higher version of kernel edition
(patch number 103640-X). The latest version is 19th. You may download
patches from http://sunsolve1.sun.com.
If you suspect that there are maybe some faults with memory modules, then
you should look at /var/adm/messages. ECC errors will pour enough light on
your suspection.
Yury Kuksa, the Sun CIS SE adviced the following:
All memory paths are ECC protected. Every ECC error is reported on
console. (Have a look at /var/adm/messages). To make ECC diag deeper you
can add the following entries to /etc/system
set report_ce_log=1
set report_ce_console=1
and reboot the machine for changes have an effect.
Well, thanks again to all brave sunners for the help!

My original question follows:
:
:Greeting Managers!
:
:I'm looking for your help and hope for your great experience. Please
:anybody who might have come accross with the problem described below, share
:your opinions please! Any hint is wellcome!
:
:After six monthes of Oracle DB server 7.3.4 exploitation, our Oracle server
:suddenly started reporting several error messages. Majority of them are
:pertain to SIGSEGV, SUGBUS signals and heap error. I'm first time faced with
:that problem. At present I have two suppositions: some "hidden" failure of
:memory modules installed inside our production server Sun Ultra Enterprise 5000
:server or perhaps I need to apply freshest patches to Solaris or Oracle.
:
:Does anybody have any idea on how to solve the problem?
