I am running matlab 2010b on centOS5.6.
Matlab opened without any error either in the computer terminal or in VNCSERVER. While running bench (of matlab) the session or the vncserver are crashing. In some cases the bench run for the first time without any problems, however it will crash the session or the vncserver on the 2-3 runs of the same code. Any idea how to solve this issue? Thanks Avi |

Welcome to CentOS.
New users should read: http://www.centos.org/modules/newbb/viewforum.php?forum=47 Please do not double post. The term "crash" is not very descriptive. Error messages and a history of what you have done to troubleshoot the problem would be more helpful. |

"crash" means that the processes are killed.
In the vncserver case I need to delete the locks file in order to run the server again. In the session case it kill the session and all the processes within it and a new login screen is obtained. |

That's pretty severe. Any problems other than with Matlab? Try running "top" to monitor memory usage, and "free -m" before and after each Matlab "bench" (benchmark?) run. May be a memory leak.

Thanks, Memory is not a problem. I have plenty before and after (see bellow) the first time runing the benchmark. The vncserver crashed on the second run.
total used free shared buffers cached Mem: 7995 1494 6501 0 31 991 -/+ buffers/cache: 472 7523 Swap: 23446 0 23446 [ I have the same problem on various machines (intel and AMD processors) all runing the same OS and software. I don't have similar problems with other softwares When running matlab without grapic mode (matlab -nodisplay) the problem vanished. However I don't have any graphics. Any sugssition how to solve this problem? |

A MathWorks bug report or other support request is all I can suggest. It does not seem to be a CentOS problem.
