Flock 0.6 running on Gentoo linux under jboss 3.0.4
This is just a guess on my part but it appears that
FlockAsyncRefresh never terminates after:

****
My guess comes from counting the number of
FlockAsyncRefresh threads hanging on the server (81
right now) and "grepping" for that error (78)...only
reason that I can see.
Here's the full trace:

    it would be great if you could get a thread dump (kill -QUIT
    pid, results go to standard out)...

    chances are, that this is caused by the http connections
    being blocked inside the JDK (it's a known bug/limitation of
    the sun http connection implementation that sometimes it
    never times out for a host with network issues)... AFAIK,
    this can only be fixed by using a different http client
    implementation, eg
    http://jakarta.apache.org/commons/httpclient/ - this can be
    implemented in a later release.

    replace URLLoader with jakarta commons httpclient...

    Since I posted this Flock has been running without those
    threads hanging open. But I had to start from a fresh
    install due to this following exception whenever I tried to

    I have a copy of the full tapestry exception page and saved
    the entire contents of the flock directory if you want me to
    send it to you for analysis. (it's very large)
    In the new install I've subscribed to the javablogs opml
    (the bulk of my subscriptions) instead of copying over
    Flocks opml and it hasn't been building up those
    unterminated threads.
    Let me know what would best help you out...

    Sorry it took me so long on this. Just having the javablog
    list subscribed took it a lot longer to build up some
    threads. I've saved the entire session if you need more info
    extracted. Here's the dump when there were 11:
    Full thread dump Java HotSpot(TM) Server VM (1.4.1_01-b01
