- The value of errno translates to “Connection reset by peer”. Suspect are something strange happening in the network or hostname resolution of the server . Maybe check for errors or dropped packets?
- protocol mis-match if you are using different versions of PBS Pro within your complex

You do not have to use PBS\_LEAF\_NAME here, please remove it.  
PBS\_SERVER=\<hostname that is reverse address resolvable and same across all /etc/hosts of headnode and compute node \>

> The value of PBS\_LEAF\_NAME should be the hostname of the interface over which you want PBS Pro to communicate, not the domain name. Unless you have multiple NICs, you should not need to set this value at all. Please try removing PBS\_LEAF\_NAME from /etc/pbs.conf and try starting PBS Pro.

This is old syntax, it is supported, better to switch to new syntax  
#PBS -l select=1:ncpus=1
