ChannelRendererFactoryImpl logs the following when its queue gets backed up:
WARN [TP-Processor3] portal.ChannelRendererFactoryImpl. Oct/02 10:40:20 - queueSize: 1094 activeCount: 20 largestPoolSize: 20
Various factors (e.g. the blocking of Socket IO) contribute to this message. The effect is that the portal remains up, but channels do not render. Several installations were experiencing this, but few log at WARN to see this message. This message should be logged at a higher level.
This patch logs the message at error level rather than warn level.
Changed logging level from WARN to ERROR
