RE: loss of connection with mod_jk(tomcat connector)
Hi Rainer, I am not much aware about JkShmFile but it was working fine with tomcat connector 1.2.43, is anything I need to setup for more loggers because even I am also not getting the actual problem.

You have configured a load balancer with 9 members, listening on localhost ports 8010-8018, but of these 9 tomcat instances only the one listening on port 8010 was up. So some requests work, because they were forwarded coincidentally to the working port, others fail, because they were forwarded to one of the 8 ports were nothing is listening and even their failover failed, because when only one out of 9 ports work, chances are very high, that the failover also hits a port where nothing listens. mod_jk remembers the failing workers (ports) for some time and will not retry to use them, but as I wrote in the ticket, you have a broken JkShmFile, so mod_jk balancers can not correctly work. Fix that problem first and make sure your ports are actually listening.

Hi Mark, We configure multiple tomcat and based on the configuration start other tomcat, since one tomcat running fine but after some time it will stop communicating, this problem we face from Tomcat Connector 1.2.46 version onwards, for 1.2.43 it works fine, please let me know if I need to enable extra loggers that will help out to understand the problem better, Thanks and Regards, Rajendra Rathore 9922701491 -Original Message- From: Mark Thomas Sent: 17 January 2019 05:05 AM To: Tomcat Users List Subject: Re: loss of connection with mod_jk(tomcat connector) External email from: users-return-29-rarathore=ptc@tomcat.apache.org On 16/01/2019 12:26, Rathore, Rajendra wrote: > Hi Team, > > > > we are using Apache Http server with basic authentication, when we try > to send some request to apache for authentication it will fail with > 401 error and when we check the JK Status, > > we found that status was not proper means instead of 'OK' state it was > 'Awaiting..'.
