Hi,
We have UTM 9 (9.501-5) deployed in AWS for VPN purposes and it was working fine for about 1 year, but since a few weeks now we're having major problems. Every day the VPN becomes unresponsive and in the openvpn.log files we see thousands of lines like this:
2017:09:21-01:00:43 vpn openvpn[6974]: TCP: accept(7) failed: Too many open files (errno=24)
Rebooting the machine clears the problem, but anywhere between 4 and 24 hours later it happens again.
A contact at Sophos suggested we update to the latest version which we did, but the problem remains.
Has anyone else had a similar problem or any idea of a solution?
Best regards
Paul
