The message is giving you a clue here. Is there any line in any file under /vob/project that contains a line longer than 2048 chars, which is a limit for some Unix commands?
Try this to count the length of lines in your files
Code:
#!/bin/sh
for file in "$@"; do
echo -e "\nFILE: $file"
awk '{printf( "%5d: %s\n", length( $0 ), $0 ) }' $file
done
Save this as linelength.sh, make it executable, and run it as
$ linelength /vob/project/*
Cheers
