<p>Dear Haider Abbas,</p>
<p>do all the nodes have access to the same filesystem? I remember
getting such (or similar) errors<br>
when I wanted to run a job on nodes with separate filesystem... In
this case be sure that each node<br>
has access to the temporary directory. See also input variables
outdir and wfcdir<br>
</p>
<p>Regards</p>
