Chet This problem has not occurred any more. We have made two changes: 1. Upgraded bash to version 3.2.39 by fetching the source code, applying the patches and compiling for the used machine (amd64, 4 processors) The change log indicates that there has been problems with parallel processes. 2. Upgraded the kernel due to a bug with inodes on huge RAM disks. Personally I think that bash-3.2.39 solved the problem. This is just to inform you that I consider this issue solved.
