751	Problems with syslog and openvpn	GoTLiuM InSPiRiT		"Hi, I'm use openvpn at this moment for internal communications between some servers. When openvpn is reconnecting or is down, nginx generate this error: 2015/04/19 22:36:45 [alert] 20460#0: send() failed (22: Invalid argument). After reconnecting/connecting, nginx never send log to remote syslog server over udp and generate error for every request.  After restarting nginx working fine.
