Re: mod_proxy apj unstable behivel

[Gryz Bug <gryzli.the.bugbear@xxxxxxxxx>]

Hi , 

We had some similiar issues where we had 2 apache instances running on the same port. Have you checked your process list for running httpd processes after the issue happens ?

Hello,

 

First of all, I’m new here, if I’m doing some stupid thing please let me to know...

 

I have a tipical configuration like bellow.

 

IP A (access1.test.com) – Firewall – Apache – Firewall – Tomcat – DB

IP B (access2.test.com)

 

I’m using apache 2.4 (httpd-2.4.6-67.el7.centos.6) and tomcat 8.0.50

I have an configuration on apache with SSL + two subdomains proxied to the same tomcat context using AJP.

Usually the configuration work fine but I have an unstable problem, sometimes, after service httpd restart, only one of subdomain doesn’t work returning 404 error, and if I restart it again it go back to work.

Sometimes access1 doesn’t work, sometimes access2 doen’t work, sometime both works fine…

And this behavior occur always after restart and don’t change before next restart.

 

I tried to downgrade the httpd service (four different version) and the problem still.

I tried to enable logging to trace5 and I couldn't get any relevant information...

I’m thinking that I’m doing some mistake in the configurations.

 

Thank you!
