Solaris 10 (5.10 Generic_144500-19) patch killed Matlab?!

1 view (last 30 days)
Hi, I recently patched my V240 box and matlab now gives the dreaded segmentation fault when I try to fire it up. I see an old reference to this question from 2009, but the patch referenced there (117461) has been obsoleted by several others. So, my question is, how to discover the culprit patch so that I can back it out? Thanks for any help - I'm new at this...

unfortunately, Oracle took a brief look at the core dump info and says the problem is within the MATLAB code. I need to follow up with Mathworks.

Oh no! Well - keep me posted. I emailed the PCA keeper (how I patch) about it as well.

MathWorks Technical Support can provide a way to work around the issue. Please contact Technical Support and refer to the internal solution 1-FPZPAJ.

Elia, what a pleasure to "meet" you again here! No, I do not know that, but MATLAB Answers is the ideal place to ask this, as there are still some users in Finance, Aero and some research institutes using Solaris.

Hi Andreas, thank you for the answer. I getting in touch with MathWorks technical suppor team and R2012a applications build on LINUX environment really do no work on Solaris. The suggested workaround is to build an applications server in LINUX and use RMI connection to access the applications from the SUN environment. I have not tried it yet. Best regards, Elia

Hello, I've the same problem. In my case matlab start only with the "-nodisplay" argument otherwise the segmentation fault occurs immediatly.
Help is very welcome ? Thank's

Haven't gotten any further. Our system behaves the same - will start with -nodisplay but crashes otherwise. Our version of Matlab is Version 7.8.0.347 (R2009a) 64-bit (sol64).
So it must be a patch that alters display, somehow.... thanks...

We were experiencing this same issue, as mentioned in the comments.
We updated our release to R2009b SP1 and then applied a patched library which Mathworks provided to us.
The patched library is:
$MATLAB_HOME/bin/sol64/libmwuix.so
I don't know if they made this available via download or not. We got it through our maintenance agreement.
Note that, once this was applied we had terrible performance issues. Also, if we tried to print to a PNG file, matlab would hang. If we tried a second time, our login session would crash. These issues may be related, somewhat, to the fact we are using SunRays.
work around this issue by starting with -softwareopengl option.
we also use the -nodesktop option here.
So, to summarise:
- apply Solaris Update 10
- install R2009b SP1
- apply patched libmwuix.so lib
- run with -softwareopengl
