Mac OS crashes

Hi guys. After Pulse Secure client update I faced OS crashes. 

Client version 9.1.8(3999)

Can anybody explain what is going on? 

 

panic(cpu 4 caller 0xffffff800cec1eff): assertion failed: (MBUFQ_EMPTY(&cfq->q_mq) && cfq->q_start == cfq->q_end) || (!MBUFQ_EMPTY(&cfq->q_mq) && cfq->q_start != cfq->q_end), file: /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.141.2/bsd/net/content_filter.c, line: 1067

Re: Mac OS crashes

BSD process name corresponding to current thread: net.pulsesecure.

 

Did the crash occur after installing the client or while connected to VPN?

 

Current thread name is not complete, can you please check if its net.pulsesecure.firewall component?

Yes, it's net.pulsesecure.firewall

Re: Mac OS crashes

@vkiryakov Thanks! 9.1R8.2 (3999) is not using KEXT (upgraded to use Security Extensions), so you can safely unload that using the following command and check the behavior:

 

sudo kextunload "/Applications/Pulse Secure.app/Contents/Plugins/Kext/PulseSecureFirewall.kext"

 

In the meanwhile, open a support ticket with Apple and see if they can provide us the root cause from the crash log.

Re: Mac OS crashes

Have the exact same issue, however the remedy does not seem to work:

 

$ sudo kextunload "/Applications/Pulse Secure.app/Contents/Plugins/Kext/PulseSecureFirewall.kext"
(kernel) Kext net.pulsesecure.PulseSecureFirewall not found for unload request.
Failed to unload net.pulsesecure.PulseSecureFirewall - (libkern/kext) not found.

 

Pulse Secure version: 9.1.8 (3999)

OS: macOS Catalina 10.15.7 (19H2)

Re: Mac OS crashes

As previously stated, please upgrade to the 9.11R8.2 Mac Client.

 

We removed the requirment for Kernel Extentions in this release and this should resolve your issue.

 

Thank you
