[CentOS] vtund error

[Brendan Minish]

I ran into this issue on a busy vtund server, it would eventually
deadlock networking 

After some detective work it appears to be as a result of this bug 
https://bugzilla.redhat.com/show_bug.cgi?id=541224

The bug report has a patch, I applied it to the kernel source and
rebuilt a new kernel RPM which I installed on our vtun servers . This
has resolved the issue for us  

please let me know if this solves the issue for you too. 

regards 
Brendan
