I guess the problem is really mine. I was somewhat expecting the connection

Uncommenting either of the last two lines makes the problem go away...

Subject: Re: Running out of connections
Hello Simon,[EMAIL PROTECTED]
Sorry to be replying so late. Connections are released when:
1) the response is fully read
2) the connection is manually released via
HttpMethod.releaseConnection() or HttpConnection.releaseConnection()
3) the garbage collector runs and reclaims any connections that are no
longer being used
The most reliable way is to manually release the connection after use.
This goes for successful or unsuccessful requests. Can you send a
sample of the code you are using that causes this problem?

With the current CVS version, I seem to be having a problem where I
run out of connections to a server. It happens if I do a bunch of
HTTP operations that fail (404, as it happens) and the reply include a
"Connection: close". If no garbage-collect happens then the
connections are not freed!
Shouldn't we expire them if we're running out of connections?
Cheers, Simon
