libc errors

[Sachin Patel]

One of our program is not working on V-class. It works on other V-class systems.

Here's the traceback.

Program received signal SIGSEGV, Segmentation fault.

If it works on one and not the other, compare your libc patches on both machines:
# swlist -l fileset -a state |grep libc

PHCO_28425 s700_800 11.00 libc cumulative patch

[Sachin Patel]

All the libc patchs are identical.

[Umapathy S]

Just a thought, please correct me if I am wrong.

The prg is getting a SIGSEGV in malloc. Is the swap correct?

cheers

_XlcResolveLocaleName looks to refer to Locale, so what is LANG set to on both machines?

And the messages refer o /usr/lib/X11R6/libX11.3 which is:

Hi Uma,
swap is good. no problem

Hi cheryl,
they are same patch as well.

Memory is the same between the machines as well?
# swapinfo -tam
# echo "selclass qualifier memory;info;wait;infolog"|cstm
# dmesg (Memory Information section)

I'd double check patch state is configured
# swlist -l fileset -a state

If this fails to find anything, I am stumped given what we know.

[Bill Douglass]

Can you run the application under tusc

http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/tusc-7.3/

and attach.

[Tim Sanko]

Sachin,

Please run swverify. If you find a patch marked corrupt, or complete, reapply please.

This will fix the installed patches:
# swconfig \*

Transient patches are not installed. Transient is similar to corrupt in that there was a failure during the install.

This is a problem because the patches include PHKL which means kernel regen/reboot and most likely dependencies.

Try running check_patches which will check for these transient patches as well as identify what might else need to be installed to correct the situation (ie dependencies). The latest check_patches should be used PHCO_27779.

It will place a report in /tmp and update the swagent.log. Let's have a look at those.

[Sachin Patel]

Hi Cheryl
I have errors in swconfig. I need to reboot the system to fix this error. one or more fileset has been remove from /var/adm/sw... I will have to reapply that patch.
I do not have check_patch patch so I will do it that at same time.
I might have to wait until system crash or have to schedule downtime. I will get back to this task once I will be finished with this.

Thanks
Sachin
