1303141457.532252 [/assert] EMERG: void PipeProducer::produce(Buffer*): Halting: Assertion (!output_eos_) failed at ../../io/pipe/ in function void PipeProducer::produce(Buffer*)

The server is also running WANProxy 0.7.2 in a vSphere VM. No problems on the server. Two other clients (HKG and HOU) are also connected to the same server and they are functioning well. HKG client is pretty much identical to the RIO client but with additional 4GB RAM. No problems noted on the HKG client. The RIO client just randomly dies without no obvious reason. I believe there is plenty of RAM and CPU to handle the load. What could be wrong?

Any thoughts will be much appreciated.
