Instead, the connection will be closed when processing a subsequent request and it is then determined that the connection can't be reused. This behavior is expected and rarely (if ever) the *root* cause of operational problems, though there are some circumstances where turning off backend connection reuse is appropriate. Is the backend server returning 503s because a lot of connections from the proxy are in keep-alive state? If so, maybe you should lower keepalive timeouts for the backend connection. **** > > ** ** > > **** > > ** ** > > I’ve found that a similar issue have already been reported :**** > > https://issues.apache.org/bugzilla/show_bug.cgi?id=50807**** > > ** ** > > Is there any correction on the mod_proxy regarding this problem, would it > appears again using apache 2.4 ?**** > > ** ** > > Thanks in advance for replies.**** > > ** ** > > ** ** > > Sébastien **** > > ** ** > > _________________________________________________________________________________________________________________________ > > Ce message et ses pieces jointes peuvent contenir des informations > confidentielles ou privilegiees et ne doivent donc > pas etre diffuses, exploites ou copies sans autorisation.
