this means that the "system load" passed a hard-coded threshold.
I am not exactly sure which value was used to trigger the alarm, but I have seen at a different customer that the warning showed up without any issues on the Web Gateway.
Did you encounter any performance problems since you are receiving the warning?
I have not had any calls about a decrease in performance but I have had about 4 of them today
I also get the same thing. It has been happening for a while now. Do not get any calls about any issues but it must mean something is happening.
This should probably be looked into.
How many users are in your network using the Web Gateways?
I avg about 2.7mb a sec of internet traffic on one and 3.9mb a sec on the other one. I have not seen this issue in the past.
