Dear Pierre:

Sorry to bother you again.

My Software is already finished. And it is tested in many computers, it worked well.

However, when I tested it in the ThinkStation Server with 64-bit Centos OS, I met a strange problem.

When I submitted jobs, they are sucessfully submitted. In the mid-way, some jobs' status are submitted or running or none, and PIPE.lock exists.

However, the jobs are not running in fact, and the jobs status stops at these status.

I terminate the jobs and submitted again, and the jobs runs again, but a little time later, the jobs are not running while the PIPE.lock exists.

Do you know the reason.

Thanks very much for your help.

Best Regards.
