You should share a single channel across threads. Only in very heavy throughput (when we start talking about trying to fully saturate a server NIC) should you even begin to consider do something else.
I can't say what bug you experienced before, but only doing one RPC on each channel at a time is simpler and is less likely to encounter bugs and interop issues. But if/when you encounter something like that, please bring it to our attention so that it can be addressed.
