[ssml] BLAST fastacmd failed to fetch sequence from database stored on PVFS2 filesystem

[Yun He]

The architectures are same: same CPU, same MEM.
In the past, every node has a local scratch pool to store BLASTDB, at that 
time, BLAST runnings are identical indeed. Recently I turn the local pool 
into a PVFS pool, but it complains ... 
And I have used BLAST 2.2.15 and the latest 2.2.17, both of the two versions 
gave the warnings.
