Connection iterrupted, reconnect fails

With the latest Client (2.9.2) and netlock activated I get frequent connection interruptions. This for itself would not be that much of a problem (even though annoying) but to make the matter even worse after such an interruption the client refuses to reconnect to any server and is stuck in a connect > disconnect > connect... loop. All that helps is manually closing and restarting the client or changing something in the settings. Here is an extract of the log:

DNS switching method is automatic (I think resolv.conf). It does not happen if netlock is disabled. The connection is also not interrupted if I manually lock the client to a specific server (checkbox "lock current"). I will add more info as soon as I find out additional details.

 

Oh, by the way, my system is Linux Mint 17.1 KDE 64 bit, running in a VM (VmWare Workstation 11) on top of Windows 8.1 64 bit. The network interface is bridged so the VM get's its IP directly from the DHCP server (router).

I am having the exact same issues on Windows, with the latest version of the software 2.9.2. Don't know if it helps, but it started today.

 

I opened a ticket attaching my logs.

I'm currently testing the experimental version of the client. From what I can tell so far this has fixed the issue. I will further monitor the situation and report back.

Have you tried the experimental client yet? I have been running it for almost 24 hours now and so far I've had only one crash of the client (I blame the experimental state for this) but no more dis- and reconnect loops.
