Pulse Secure 5.1.5 and El Cap

[jpayne]

Sometimes works fine, sometimes gets in a loop where it keeps creating and destroying utun0:

Thu Oct 29 13:21:08 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:09 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:10 EDT 2015
utun0: flags=8051 mtu 1400
inet --> netmask 0xffffffff
Thu Oct 29 13:21:11 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:12 EDT 2015
utun0: flags=8051 mtu 1400
inet --> netmask 0xffffffff
Thu Oct 29 13:21:13 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:14 EDT 2015
ifconfig: interface utun0 does not exist

Some interesting log entries:

This is also a little surprising to me:
10/29/15 1:10:06.353 PM dsAccessService[72]: objc[72]: Class DSCookieStore is implemented in both /Applications/Junos Pulse.app/Contents/Plugins/iveConnectionMethod/iveConnMethod.dylib and /Users/jpayne/Library/Application Support/Juniper Networks/SetupClient/juniperSetupDll.dylib. One of the two will be used. Which one is undefined.

Jpayne,

We've had a couple of other reports of intermittent/occasional issues on El Capitan. We are currently investigating. Would you be willing to email a Pulse Log bundle to "pulse-universal-feedback@pulsesecure.net"? If so, I'll make sure the proper developers take a look. Alternatively, your IT administrator could reach out to our support organization at http://www.pulsesecure.net/support and create a formal tracking ticket.

I'm seeing similar log messages on my system using Pulse 5.1.7 and OS X 10.11.3:
