Thanks a lot for your attention. I have tried to follow your suggestion but again there are problems.
1. The result of ls -ld /dev/shm/ is: drwxrwxrwt 2 root root 40 2012-03-23 16:57 /dev/shm/ 2. I ran the python script (as ordinary user, not superuser) you suggested; the response was: Error creating semaphores. On Linux, make sure /dev/shm is mounted and user-writable. What do I do now? Also please tell me what is expected if the python script runs without any problem and then how do I solve my original problem? Will my problem be automatically solved by running the python script? Thanks.
