starting 2 tunnel concurrently crashes kernel in 10.7 GM #185

Closed GoogleCodeExporter closed 9 years ago

NOTE: We suggest that you post on the Tunnelblick Discussion Group before
submitting an "Issue". (http://groups.google.com/group/tunnelblick-discuss)

What steps will reproduce the problem?
1. start tunnel config A and tunnel config B at the same time
2. they try to start both concurrently
3.

What is the expected output?
both tunnels should be up and running ... - it works when you let each tunnel 
come up completely and then start the next one.

What do you see instead?
a kernel panic (it seems that both openvpn connections run ifconfig during the 
crash) because of a crash in kext.

What version of Tunnelblick are you using? On what version of OS X?
tunnelblick 3.2beta22 , MacOSX 10.7 GM

Please provide any additional information below. Please include your
configuration file and the contents of the OpenVPN Log window (including
the first few lines with version information), but remember to remove any
sensitive information such as IP addresses.

It would be very helpful to know if this happens when running Tunnelblick 
3.2beta22 under OS X 10.6.

I can't reproduce this, trying with two, or even three, simultaneous TUN 
connections. I tried it about a dozen times with no problem.

Can you try it without the "user nobody", "group nobody"? Maybe it has 
something to do with that.

Can you post the OpenVPN logs? After restarting, they will be located in 
/Library/Application Support/Tunnelblick/Logs and have odd names that include 
the configuration name.

And it would help if you could post a log from a successful (one at a time) 
connection.

Thanks.

I believe this is related to Issue 186 -- that is, it is not specific to having 
two connections simultaneously, but has something to do with restarting 
connections under Lion.

So I have marked this as a duplicate

I have the very same issue. Tunnelblck connects, reconnects after about 20 
seconds and randomly I get a kernel error.

Tunnelblick 3.1.7 (build 2190.2413)
OpenVPN: 2.1.4
OSX: 10.7.2

Tunnelblick 3.1.7 does not work with 10.7; use 3.2beta32. See the Downloads 
page for details.

jsut upgraded to 3.2.3 build 2891.2932. the previous version was crashing my 
mac os x lion 10.7.2 like a hell. Crashes could happen each 30 minutes. 
Situations with 2-3 crashes per week were normal. server vpn software: openvpn. 

ill monitor the new version.
