I still have the unit in question; however, since the segfault  
happened inside libc, I won't be able to reproduce it easily here.

Just to be sure, this is the same NUT 2.2.2 (from Fedora Core 9 RPMs)  
that you mentioned in the last email?

Also, I am copying the nut-upsdev list so that other people can find  
this email thread.

Hmm, the device shouldn't have detached here.

It looks like we patched this in the trunk, so it would be released  
as part of NUT 2.4.0. I'm not sure if they will be releasing NUT  
2.4.0 for FC9, so I am attaching the updated files that you would  
need to rebuild the NUT 2.2.2 RPM.

Grab the SRPM from here: http://rpmfind.net/linux/RPM/fedora/updates/ 
9/SRPMS/nut-2.2.2-1.fc9.src.html

Install it (probably "rpm -i nut-2.2.2*.src.rpm).

Copy nut.spec and nut-2.2.2-tl-reconnect.patch into /usr/src/rpm/ 
SPECS and /usr/src/rpm/SOURCES, respectively.

cd into SPECS and run 'rpmbuild -bb nut.spec'.

Charles:

Yes, this is the same rpm from the FC9 distro.

I'll give rebuilding the rpm a try based on your instructions.

Thank you,

Charles:

Ok, I followed your instructions and rebuilt the RPM, then upgraded it on my
system.  I'll keep you posted as to whether the problem comes up again.

Thanks very much for your help,

*Bradley
