The first bell it rang was that a disk issue condition could happen. A chkdsk on the posmaster in your scripts might help.

Also in that debug line, I think the key word is "other". It doesn't matter SYSTEM is "rwx" on the postmaster, but you must make sure other (the righmost rights) is at least "r-x" (as ValidateBinary suggests). So a "chmod <put_proper_options> postmaster" in your scripts, could also be a good ideea.
