bugs in mod_webapp

[Donald Ball <ba...@webslingerZ.com>]

new thread name since i've got me some real bugs to note, not just my
stupid compilation and configuration problems.

1. when tomcat is restarted while apache is running, mod_webapp returns
errors for all further tomcat requests. apache's error_log reports:

[Thu Jun 28 23:45:55 2001] 17320 (pr_warp.c:348) Cannot read from socket

and then keeps repeating the 'We are disconnected' bit for each request.

2. after apache has started, the first request always times out.
catalina.out reports:

java.lang.IllegalArgumentException: addChild:  Child name

        at

[org.apache.catalina.connector.warp.WarpRequestHandler]
    End of request
[org.apache.catalina.connector.warp.WarpRequestHandler]
    Thread exited

but after that, it's fine.
