Description Christian Goetze 2004-04-30 17:41:18 UTC 
Description of problem:

any rpm operation hangs, strace for "rpm -qa" attached.

Version-Release number of selected component (if applicable):

assam> rpm --version
RPM version 4.1

How reproducible:

Not sure how to create the initial state. I suspect there may have 
been an aborted rpm operation which may have created an inconcistent 
state. Rebuilding the rpm database seems to fix it, but after two or 
three rpm operations the hang is back and will happen reliably at 
every subsequent operation. I can provide a complete snapshot 
of /var/lib/rpm is it is helpful.

strace of "rpm -qa". The process needed to be killed with "kill -9".
Comment 2 Jeff Johnson 2004-05-04 13:39:18 UTC 
Try
    rm -f /var/lib/rpm/__db*
Did that fix?
Comment 3 Christian Goetze 2004-05-04 13:56:04 UTC 
Yes. On the mailing list, you pointed me in the right direction 
(SIGPIPE), and I now save the output of rpm -q into a temporary file 
prior to further processing.
