Tuxedo Error: masked synchronous signal 10.

Hello Experts,

I am not able to start tuxedo on HP unix machine. Following are some details:

uname -a
HP-UX opqa1 B.11.23 U ia64 0409362437 unlimited-user license


$ tmadmin
[HP ARIES64]: ***** Log time: Mon Sep 13 17:29:48 EDT 2010 *****
[HP ARIES64]:

Re: Tuxedo Error: masked synchronous signal 10.

Unfortunately you may need to change your application.

You must never block signal 11 and signal 10 (SIGBUS).

The abort occurs because the kernel notices that there is only one thread and if you block a signal, then no forward progress will be made, if you get that signal, while blocked.

Did you get a core file that you can analyze to see where you are getting the signal 10?

Hello Dennis,

No I am not getting any core file.

Also please note that I am simply running some command files from Tuxedo like tmadmin or tmboot -B . I am not even trying to start my application tuxedo services.

Can you please let me know how to find out where the signal 10 or 11 is getting blocked as you mentioned?

Also, I forgot to mention in my earlier post that the tuxedo software and my tuxedo application were running fine for almost one and a half year. It is only since last couple of days or so that I am seeing this issue.

Thanks in advance.

You might try installing the recommended Aries patch: PHSS_41098

If you don't get a core file, you would have to use a debugger.

Anything change? I assume you have been running this on Integrity for longer than that?

Hello Dennis,

There were no changes to the HP machine before we started seeing this Tuxedo error condition.

As far as I remember, Tuxedo software and my tuxedo application have been running fine on this machine for atleast one and half year.

How do I find out if the patch PHSS_41098 you recommended is already present on this HP Unix machine?

Thanks

Hi ShivS:

A way to easily find out whether or not you have the patch in question or a superseding one with:

# show_patches -a -s -l product|grep PHSS_41098

Hi James,

Thanks for the show_patches command line. I used it on my machine and nothing showed up in the result. So I will have to install this patch PHSS_41098.

Can you please tell me where can I find this patch? Also how do I install (or apply) this patch on this machine?

Thanks in advance.
ShivS.

Re: Tuxedo Error: masked synchronous signal 10.

You can get it from the ITRC site.

http://www11.itrc.hp.com/service/patch/mainPage.do

However; if you do not have a current HP support agreement, you had better be quick off the mark because the service becomes restricted from September 18!

Hi ShivS:

Since you appear to be unfamiliar with HP-UX patches and the HP-UX patch mechanism, I would urge you to look at:

http://www.docs.hp.com/en/5992-6582/5992-6582.pdf

Pages 18-22 discuss how to install a single patch. As noted, patches are obtained from the HP Patch Database:

Hi James,

The Unix admin department at my workplace with be performing the patch application. I simply told them which patch to apply.

Thanks for your help.
