Hey again guys! After ~2 weeks of system uptime with ssl inspection enabled.

Today our network got stuck.

I could only login via console port and reboot the device

Memory usage got stuck at 99% .

Now sometimes I see the error


SSL Inspection Reach maximum number of sessions 3000:3000!

Creating session entry failed. Pass this session!

    Hi @sk8erbender,

    On ATP500, the maximum concurrent session for SSL Inspection is 3000.

    The concurrent session is related to the amount of traffic.

    If it reaches the “Maximum Concurrent Session”, ATP500 will pass this session without inspections.


    About the memory usage, use the command to show the memory status on console.

    Router# show mem status all
