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?

Re: Controller not responding

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

Re: Controller not responding

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 ?
