I am getting the following error messages, I need to know what causes them (why foxweb thinks it should display the message).

Here are some details of whats running:
Window 2003 std sp2
Foxweb 4.3
20 foxweb channels
3gb mem buffer

Error Messages:
Channel Timeout Error - No Available Channels
FoxWeb Broker Timed Out
FoxWeb Service Has Been Temporarily Paused

We are currently testing the scripts under heavy load (what loads we can get away with)

Current loads are about 12 scripts per second

We get no Errors in the error log and no restarting of channels in the start.log
