LiteSpeed Support Forums - LSWS 4.0.x and AJP app

I'm running into some nasty connection errors (which lead to 503 occuring frequently on my site) with an Django app running trough flup's AJP protocol and a LSWS connector.

Log from flup-ajp django daemon:

Code:

2009-08-26 10:40:38 : Exception caught in Connection

Traceback (most recent call last):

Vhost's external app config:

Code:

Type: Servlet engine

Address: 127.0.0.1:3033

Max Connections: 100

Connection Keepalive Timeout: -1

Initial Request Timeout: 60

Retry Timeout: 3

The flup-ajp django process is run by this command:

Code:

/usr/bin/python $DIR/manage.py runfcgi method=threaded daemonize=false \

        maxrequests=0 \

        maxchildren=300 \

        minspare=30 \

        maxspare=60 \

        protocol=ajp \

        host=127.0.0.1 port=3033

I'm suspecting, that LSWS is the cause here, as using apache with mod-jk on the same flup-ajp django instance (yes! it's lightning fast) yelds no errors at all.

The connection count from LSWS to the app floats between the max allowed connection limit in LSWS while operating normally (no 503 errors), and drops to:

Code:

 ~$ netstat -a -n | grep 3033 | grep ESTABLISHED  | wc -l

29

while the 503 errors occurs.

The bug has been observed on every 4.0.x version. Currently testing with 3.x

Help, please? :)
