Bug#468289: apache2.2-common: Segfault when checking BalancerMember status via handler balancer-manager
Package: apache2.2-common
Version: 2.2.3-4+etch4
Severity: important
After upgading to the latest build of apache2 (From a Build in Sept
2007), visiting a BalancerMember's status page to enable/disable/see
details results in a segfault in apache.
I noticed this, because one of our servers had a build newer than
another one, and with identical configs on both hosts, I could view the
balancerMember's status on the older version.
After an apt-get upgrade that included apache, the server that did work,
begain to fail.
Web browser sees a blank page.
