Re: [Openvpn-users] Assertion failed at mroute.c:349

[Paul Mitchell <paul.mitchell@xxxxxxxxxxxxxx>]

Hi,

We've now tried using the RC versions. The problem still persists.  I 
happened to have a telnet session on just now when the "Assertion failed 
at mroute.c:349" message appeared because of the connection failure.

The log was set to verb 3

Will also have a look at runit that Charles Duffy spoke about.
