If you are running into TFO limit it means that the WAE has reached its limit in terms of number TCP sessions it can optimize.

Can you give us the exact alarm message you are seeing on CM for that particular WAE?

Btw, what version of code you are running on that WAE will be helpful.

Hi,

the exact message is "Minor: The TFO accelerator is overloaded (connection limit)"

i'm running 4.1.1b.

Now i got 4GB RAM and this means 6k connections. At the moment i have 4k conn.

#sh tfo detail

Rafael,

Please try upgrading to 4.1.1d. Many issues have been resolved since 4.1.1b, including some AO issues that resulted in TFO overload situations.
