Alan,

I can find no reason for the pqact(1) process to misbehave in this
manner.

Would you please put the pqact(1) in question into VERBOSE logging mode
and send me a typical log-file excerpt showing the problem.

Regards,
Steve Emmerson

The output of the decompress process (from Harry Edmond) is very basic 
and really doesn't give too many messages, error or other wise.  The odd 
thing is it was working on Friday thru to Saturday and then started 
having problems.  Nothing on the server had changed.  When I recycled 
the ldm daemon, it started writing again with no problems. 

Very odd situation. 

Alan.

The above message contained the following:

"pbuf_flush (3) write: Broken pipe" on the NEXRAD Level II decompress

The pqact.conf entry is:

NEXRD2&lt;tab&gt;^L2-BZIP2/((....)/(........)(......).*)&lt;tab&gt;PIPE&lt;tab&
gt;-close&lt;tab&gt;/home/ldm/nexradII/bin/nr2_decomp

The "Broken pipe" message means that the pqact(1) process couldn't
write the NEXRAD2 data-product to the "nr2_decomp" decoder-process
because the pipe to that process was closed.  This could occur
because the decoder-process closed its end of the pipe or because the
decoder-process terminated.

Does the error-output of the decoder-process indicate any problem?
