I/O Error: There is no process to read data written to a pipe

[macrun95]

I'm getting an error message when I try to access a sqlserver from Unix (AIX). Has anyone seen this error before and could possibly give me some help and direction? The error is:
I/O Error: There is no process to read data written to a pipe.
java.sql.SQLException: I/O Error: There is no process to read data written to a
pipe.
