Hi, I have a small java application that uploads images into the lustre filesystem. When I try to upload images from the application, the MDS server crashes and kernel panic happens. I have attached the ouptut of the ''dmesg'', and the lustre log file. MDS server crashes only when I try to transfer files from the application. Normal dd command inside the lustre file system works fine. I am able to move files manually. But not able to do with the java application.

There is no fix it seems, but perhaps you can post there and try with a debugging patch from there to help to find the issue since you can hit it reliably. Thanks. Bye, Oleg
