socketRead0() never returning

List friends,

I'm having a problem interacting with an HTTP based publish/subscribe system (from a company called KnowNow). At 12:30 AM, the KnowNow server pauses for a few seconds to save a snapshot of memory to the disk backing store. When that happens, the connection from my application hangs and NEVER returns. Below is the backtrace:

   0: java.net.SocketInputStream.socketRead0()  line -1
   1: java.net.SocketInputStream.read()  line 129
   2: HTTPClient.BufferedInputStream.fillBuff()  line 172
   3: HTTPClient.BufferedInputStream.read()  line 110
   4: HTTPClient.StreamDemultiplexor.read()  line 273
   5: HTTPClient.RespInputStream.read()  line 155
   6: HTTPClient.RespInputStream.read()  line 115
   7: HTTPClient.Response.readResponseHeaders()  line 971
   8: HTTPClient.Response.getHeaders()  line 693
   9: HTTPClient.Response.getStatusCode()  line 263
  10: HTTPClient.RetryModule.responsePhase1Handler()  line 83
  11: HTTPClient.HTTPResponse.handleResponse()  line 782
  12: HTTPClient.HTTPResponse.getStatusCode()  line 204
  13: com.knownow.microserver.KNJServer.publish()  line 1259

Has anyone else experienced a socket read that never returns? I'm using WO 5.3.1 and Java 1.4.2_09 on a PowerMac Dual 1.8GHz running 10.4.3.

Any thoughts or ideas would be greatly appreciated!

Thanks,
Ken
