qmailanalog fatal:

[B. Engineer]

Hello:
        I am running qmailanalog0.70.
It dies with the error

bin/matchup </tmp/q > qoo
matchup: fatal: unable to write fd 5: file descriptor not open

It dies at the same size everytime
rw-r--r--   1 root     other    36934041 Oct  6 16:13 qoo

I know I have enough space on the system and everything else appears to 
be fine. 
Any ideas
