Controller not responding

    Hi,

     

    we have some strange problems with our setup:

     

    We have a single 3400 Controller which is sometimes not responding on any webserver-port. No WEB-GUI, no Captive Portal. A few seconds (or minutes, or sometimes hours) later, anything is fine... There are no problems to access the Controller via SSH.

    We checked some things:

     - There are no STP-Options enabled on the whole networks setup

     - we have a CPU-Load at about 1%

     - there are only about 10 Clients connected

     - there are no DoS-Attacks or somethings similiar to that

     - we tried different Software-Versions (6.1.3.6 at the moment)

     - we tried to access the controller via different physical ports, directly at the front of the controller - same mistake.

     - we checked all available logs for errors - nothing

     

     

    So any idea? TAC?

    Have you confirmed there is not an IP conflict?  Can you give the controller another IP to see if it responds?

    Maybe it is an issue with the httpd (apache) process? Do you see anything if you do show cpuload current? Or 

    show ipc statistics httpd stm ?
