Hello .*, I want to increase the amount of the maximum concurrent connections-clients that our storage element(DPM_mysql) can handle. Some of our users use our storage element for writing some thousands of very small files. I suspect that our storage element cannot handle so many connections concurrently so it queues some of them for a long time and discards others, resulting to failures in SAM tests. Although, running all the commands on my own I have no problems. Any suggestions? thanks a lot! P.S. I have informed the users for their "denial of service attack" and they stopped sending jobs. Although, many of the already sent jobs are now sending files. -- Asterios Katsifodimos High Performance Computing systems Lab Department of Computer Science, University of Cyprus http://grid.ucy.ac.cy
