Have you restarted all the spacewalk services since the update was installed? <div style="font-family: arial, sans-serif; font-size: 12px;color: #999999;">-- Sent from my HP Pre3</div> <hr align="left" style="width:75%">On Mar 11, 2013 12:48 PM, Coffman, Anthony J <Tony.Coffman@snapon.com> wrote: Sorry for top posting.

A newer one was released with RHEL 6.4 (https://rhn.redhat.com/errata/RHBA-2013-0327.html). The old one had problems with ref-counting and leaked connections. For me the problem with high connection count was solved by the update.
