Brent,

You appear to be having a problem with the redirection of the bufr
logging from stderr to /dev/null. The sporadic behavior depends on
whether the attempt to open /dev/null fails. The 5.9.4 distribution uses
the melBUFR library supplied with GEMPAK,
where previously I had utilized separate routines (that is why you see
additional
log messages with the 5.9.4 distribution).

I have re-written that code and tested. The distribution files are being
reposted to
the download area at this time.
