I'll throw some more fuel on this fire:

[root at java /root]# ps --version
procps version 2.0.6
[root at java /root]# echo $COLUMNS
122
[root at java /root]# ps -ef|grep CGServer
root     19917 19894  0 18:52 pts/7    00:00:00 grep CGServer
[root at java /root]# ps -ef|grep CGServer|wc -l
      1
[root at java /root]# COLUMNS=122 ps -ef|grep CGServer|wc -l
      108

COLUMNS was set automatically on login from my terminal dimensions. So how
does one explain the behaviour above ?
