Troubleshooting / Wanos Services incl. WebGUI become unresponsive after some time
« on: May 17, 2018, 04:00:07 PM »
I'm in the process of evaluating Wanos. Initial test look promising but I'm facing the problem mentioned in the title. Use-case is:
svn repo synchronization over low performance OpenVPN Site-to-Site links.
Network-Architecture: SVN Server HQ -> Wanos HQ (Tunnel-mode) -> Firewall HQ -> OpenVPN Site 2 Site Link -> Firewall BO -> Wanos BO (Tunnel-mode) -> SVN Server BO
Setup works as expected (but only without tcp-x), peers are healthy, optimization ratios look promising and during "normal use" no issues came up.
But when I try to do the initial repo sync with long-term link saturation the WebGUI times out after some time and data stops to flow/svnsync becomes unresponsive (resulting in a broken repo with tons of zombie-locks). most of the time it happens with the BO-Appliance but sometimes also on the HQ-end. Local login on the VMs is still possible and normal operation resumes after a reboot.
