Hi all,

The server.7721.log has error messages that indicate that there is probably no file space available at that time or there is some error condition that prevented flushing the buffer from a node. Is there a memory/disk space setting that can change this?

<logEvent id="133665" timestamp="1415545216742" level="ERROR">

That doesn't appear to be a setting problem, it appears to be that whatever you were connecting to has closed or ended abnormally.
What node was produced this error?

It was reported that such messages have been seen often and not due to any particular node. I am trying to confirm this. Is this a node level error?

Are nodes failing? or is this simply a set of messages in the server log?
I think this message is (also) produced when a BRE session disconnects unexpectedly. If you are ONLY seeing this in the log (and no nodes are failing) then this message can be ignored.
