unexpected EOF on client connection during pg_dumpall

I am currently getting a “unexpected EOF on client connection” when running pg_dumpall from a bash shell script in cron.  I have looked online to see if anyone else is having or have had this problem without any luck.  I am hoping someone can point me in the right direction to determine what is happening.  When I run the command manually it works.  The command that I am running is as follows using a password file to get the password:

/app/PostgreSQL/9.1/bin/pg_dumpall –h hostname –p portnumber –f filename –U backup

I am currently running PostgreSQL 9.1.9 on Centos 5.9 where the server is a VM instance.  Below is the output from my log.  I have changed the actual hostname to hostname for security reasons.
