pkts received ( 9 to 12 )
pkts processed (7 to 9 )
pkts sent ( 12 to 22 )

Somtimes there is a number in brackets left of pkts sent. It gets red, when above 20 I think.

What is it and could it cause problems?

I recognize some battle.net errors. While playing i got chat message, that i lost connection to battle.net and same time followed by message, connection established.

Number in brackets goes up to 38 for short time sometimes.
(sorry for new post, but edit of above post did not work)

the number to the left in parents is the number of messages in the queue.

messages that are in the queue for more then 2 seconds are dropped.

battle.net is having issues as they start moving towards WoD alpha
