Cisco AnyConnect VPN high CPU (system) usage
My workplace has installed a Cisco VPN that uses a physical RSA token.
The client software is downloaded from the server, called AnyConnect. It's a combination of a java applet and a linux binary. The Java applet fails to work, however, the VPN web page provides a link to download vpnsetup.sh.
I first downloaded vpnsetup.sh to my laptop. It is an install script in which a bunch of binaries are embedded. After the installation was done, I found out it installed an /etc/init.d/vpnagentd /opt/cisco/vpn/bin/vpnui, and brought along its own version of libcrypto.so.0.9.8 and libssl.so.0.9.8. The vpnui program is a gui front end for the VPN.
It works fine on the laptop.
I then repeated the process on my desktop. It also works there, except vpnagentd is using 100% of one of the two cores is spinning, about 16% in user mode and 84% in system.
Laptop: Linux 18.104.22.168 Pentium Mobile 1.6GHz

Anyone familiar with Cisco AnyConnect or with this problem?
