We are still facing this issue on 2212, running view client 2303. Some of out clients we can attribute to a memory utilization issue on the thinclient and adding more ram has bought us some time. We had to look the PID table and system logs to see that the view client or a component of it was being killed by OOM on these devices. What attributes to the high usage is still to be determined. We even tried to run with no client re-directions and all plugins disabled, but it still happens.
