Summary 0002660: HTTP/1.1 503 Service Temporarily Unavailable
Description Dear

We have a web server for a customer which runs on W32 Binary versions of Apache 2.X and Resin 3.1.6
The servers are Windows 2003 Servers. All equiped with 2 or 4 GB RAM , Dual processors XEON.

We continuosly receive the following error from our monitoring system.
About every 10 minutes or so , even though the website is hardly visited (so no constraints on busyness)

status code: 503, status string: HTTP/1.1 503 Service Temporarily Unavailable

We have upgraded to the very latest stable release of resin , but we keep getting this error.

Can you provide us with some pointers to start cheking this error ?

We think it has something to do with The version of Apache (2.X) together with Caucho because on another system
we use Apache 1.x , on a very heavy loaded system (+120.000 unique visitors per day !!) and it NEVER happens ...

Kind Regards
Bram Van Daele

Updated the default load-balance-idle-time calculation to create a bigger gap. The stress testing here doesn't show any 503s at all.

We do recommend using Resin's load balancer when possible, since it's more intelligent about socket pooling and sharing.
