Hi Scott,
There is a bug in pvfs2 with the new version of db. I don;t know how
others have not hit this issue just yet..
My fix is defly not correct. Sam is probably the best person to
figure out this breakage. If not, I will try to probe tonight.
Can you roll back to an earlier version of db and run configure with
--with-db=<path to db>?
BTW: It is awesome that you have gotten the MX stuff working!
Everything looks great!
thanks,
Murali

Hi all,
I am trying to test pvfs2 on some amd64 machines running 2.6.17.11
with db-4.5.20. I am seeing some of the same error messages as the
mentioned on this thread earlier. I used Murali's patch and I no
longer see the infinite loop. I can ping and statfs without problem.
When I try to cp, however, I get:
% ./sbin/pvfs2-server -d ./etc/fs.conf ./etc/server.conf-shower01

The trove error happens at copy time. The double free happens after I
hit ^c.
If I restart the server and I try to use ls on the directory, I see
on the server:
