Hi, I'm seeing that with Apache 2.4.12 on Solaris when setup with mod_proxy to 2 tomcat instances when we bring down 1 node for maintenance the first client to try and access that node gets a Internal Server Error. Any requests after that (and for other sessions) are balanced correctly onto the other node.
Is this normal? Is there a way for it to just balance over to the other node without returning the error? My conf: <VirtualHost *:80> ServerName somedomain.com ProxyPass /share http://127.0.0.1:8181/share ProxyPass / balancer://cluster/ stickysession=JSESSIONID nofailover=Off # define the balancer, with http and/or ajp connections <Proxy balancer://cluster/> Order allow,deny Allow from all BalancerMember ajp://127.0.0.1:8010 route=g1 BalancerMember ajp://127.0.0.1:8011 route=g2 </Proxy> </VirtualHost> I see in the apache logs the following: Wed Apr 20 11:04:11.739700 2016] [proxy_ajp:error] [pid 58313] [client 10.12.32.251:56869] AH00992: ajp_read_header: ajp_ilink_receive failed, referer: https://example.com [Wed Apr 20 11:04:11.739713 2016] [proxy_ajp:error] [pid 58313] (120006)APR does not understand this error code: [client 10.12.32.251:56869] AH00878: read response failed from 127.0.0.1:8010 (127.0.0.1), referer: http://example.com [
