AnyConnect 3.x Linux High CPU

[yaroslav.sapozhnik]

Cisco AnyConnect version 3.1.03103 CPU usage is 100% for one of the cores. The process name is 'vpnagentd' is causing high CPU when connected to VPN. Linux kerner version is 3.19.1.

Is there any way to debug it?

Thanks.

Hi Yaroslav,

I've had this problem too.

I found that this happened when I used the IcedTea Java bundled with the operating system I use -- Ubuntu. When I use the JRE from Oracle's site, this doesn't occur: the CPU usage remains reasonable at least when there is no high traffic over the VPN connection.

If you decide to fix the problem this way and install Oracle JRE, please make sure your browser uses the right version of Java plugin if you launch the AnyConnect client from a web page or, if you start it from the command line, make sure the right java binary is used by adjusting your PATH variable.

I'm not using this VPN solution anymore. Thanks for the info though!
