Why do I get error when submitting a job to an LSF cluster from a Windows MATLAB client?

When submitting a job to an LSF cluster from a Windows client I receive the following error:

 ??? Error using ==> distcomp.lsfscheduler.pSubmitNonSharedJob at 128

 Error executing the LSF script command 'bsub'. The reason given is 

Oct 12 12:35:41 2007 3852:3304 3 7.01 createPipes: procStart_ failed cc=75 error=6

 Oct 12 12:35:41 2007 3852:3304 3 7.01 getEData: createPipes() failed, Unable to fork child.

 Request aborted by esub. Job not submitted.

If I try to call the LSF cluster directly using the bang operator (!), I also get the same error.

For example running:

!bsub sleep 10

throws the same error within MATLAB. I can run that same command in a Windows command prompt without error.

This error may be the result of how MATLAB is making the call to system commands. This issue is present in MATLAB versions R2006b - R2007b. To resolve this issue, try downloading the appropriate .mexw32 file. Once you have the appropriate .mex32 file, launch it once before making calls to the LSF cluster.

If this resolves the issue, you will need to call the .mex32 file each time you start MATLAB. This can be done by placing the file in the MATLAB startup folder, or by creating a startup.m file that calls the file at launch time.
