Dear all, we are driving O-VPN 2.3.2 on Fedora20. Since we have quit many permanently connected O-VPN clients, we have started three O-VPN processes, listening on three different ports and setting up three different tap interfaces:
Today, all three O-VPN processes crashed suddenly, whereas we found following error: ip-172-16-128-101 openvpn[654]: <CN>/172.16.253.10:44214 Could not create temporary file '/var/tmp/openvpn_cc_1bd37815cbacd70936015e40e25198aa.tmp': Too many open files We did not find any helpful information, neither in the the mail-archives, nor in other forums/panels, beside something related to user/password authentication (openvpn-auth-pam), which we are not using (using TLS-server) and also lsof did not provide any helpful information to correlate this error to a (file-) resource problem https://forums.openvpn.net/topic13474.html https://community.openvpn.net/openvpn/ticket/201 After this happened, we found: - in /tmp: -rw-r--r--. 1 root 0 Jul 18 10:51 vpn3_sema_15198 #sema files laying around - in /var/tmp -rw-------. 1 root 0 Jul 18 10:51 openvpn_cc_0e211df697b9f5620da89bd05f44ef48.tmp Deleting of the sema-files and restarting O-VPN brought back everything to life. Has anybody ever experienced something similar, can this be a bug and what could be the corrective action to overcome, this to repeat again?
