Load balancing with Mod_cluster and JBoss server will occur 503 error (loss the response) finally

[renqilei]

Environment:

Mod_cluster: Version 1.2

JBoss: eap 6.4

Situation:

System is adopted Mod_cluster to realize load balancing, I have configured everything by default following the handbook; While it will occur a large quantity of 503 error from the server.

Additionally, the configuration of executor is bounded-queue-thread-pool, while size of core, queue and maximum are 60, 60, 500 respectively. I am not sure this is essential for my issue.

Sorry I am a newbie, so please kindly tell me where I should go and what I should check for, in order to solve the problem.

Thanks very much if anybody could give me some advice or inspiration.

Dear Qilei,

it is utterly impossible to help you without seeing your Apache HTTP Server error_log on LogLevel debug and your EAP server.log on at least INFO.   Apache HTTP Server log is more important though.

Furthermore, could you post your Apache HTTP Server mod_cluster and mod_proxy (if any) related configuration?

1.2.x is Deprecated

mod_cluster 1.2.x is deprecated. If you find a bug, it will be fixed in master and 1.3.x branch.  We will do our best to help you with configuration on any version though.

Cheers
