troubleshooting a process that crashes within 3 mins
I have an agent software on RHEL6.x that would always once started either by
/etc/init.d/xx_agent start
or
service xx_agent start
Have tried uninstalling & reinstall but it did not help. I've installed this very
same rpm on almost 300+ RHEL6 VMs but they stay while only on that 5 RHEL
VMs, they simply crash as "ps -ef |grep xx" shows.
Nothing eventful is found in /var/log/messages & even with 'extended' trace
provided by this principal, they found nothing.
Usually Redhat requires us to run sosreport (or is it now sysreport?) & send to
them? Will this help & specifically where would Redhat look at in the sysreport
to check this?

Is this about 32 or 64 bit RHEL5? Do you have anti-malware?
Antimalware is crashing in question... luckily not pulling kernel along.

There's 2 processes started by this ds_agent script: one is an agent for DS
while the other is the antimalware process that it spawns.
Both crash within 3 mins.
How do I use strace in RHEL6?
& how to run it in gdb or valgrind?

All the 5 affected VMs are on RHEL6 x64 and the hundred over VMs
that I got the same agent working are also on RHEL6 x64
that I got the same agent working are also on RHEL6 x64
So if they are the same then you would need to compare them and find the difference. Possibly clone a new one for testing.
if we look at formal software requirements it is only old uniprocessor RHEL6 kernels supported (i wonder if it means that support sends you away if you have problems on SMP machine)

Think in Solaris we have truss & in certain flavours of UNIX, there's systrace. What's the
equivalent for RHEL6 ?
Let me know if you would like the script for /etc/init.d/xx_agent attached here for further
investigation
