Hello -- we're using 0.72. We're looking at the source, but want to be sure. :-)
We create a single ConsumerConnector, call createMessageStreams, and hand the streams off to individual threads. If one of those threads calls next() on a stream, gets some messages, and then *blocks* in some subsequent operation (and blocks for minutes), can it potentially cause all other threads (calling next() on other streams) to block too? Does something inside the ConsumerConnector block all other stream processing? This would explain some behaviour we're seeing. Thanks, Philip
