[Openvpn-users] Multiple "PUSH:" line logged?

[Ralf Hildebrandt <Ralf.Hildebrandt@xxxxxxxxxx>]

I'm debugging a strange "connection hanging" problem with our openvpn
setup here. Sometimes, the VPN connection would hang (no packet goes
through for about 10 seconds, according to the mtr output)

One thing I noticed is that the connection is "hanging" whenever I see
this in the log:

Jan  2 23:01:35 vpn-gw-int ovpn-server[12799]: aweima.vpn.charite.de/91.63.211.238:62245 PUSH: Received control message: 'PUSH_REQUEST'
Jan  2 23:01:35 vpn-gw-int ovpn-server[12799]: aweima.vpn.charite.de/91.63.211.238:62245 PUSH: Received control message: 'PUSH_REQUEST'
Jan  2 23:01:35 vpn-gw-int ovpn-server[12799]: aweima.vpn.charite.de/91.63.211.238:62245 PUSH: Received control message: 'PUSH_REQUEST'
Jan  2 23:01:36 vpn-gw-int ovpn-server[12799]: aweima.vpn.charite.de/91.63.211.238:62245 PUSH: Received control message: 'PUSH_REQUEST'

(I didn't duplicate the lines, they were logged that way!)

I'm seeing this with some clients only:

Jan  2 23:03:50 vpn-gw-int ovpn-server[12799]: brost.vpn.charite.de/87.185.222.132:1155 PUSH: Received control message: 'PUSH_REQUEST'
Jan  2 23:03:50 vpn-gw-int ovpn-server[12799]: brost.vpn.charite.de/87.185.222.132:1155 PUSH: Received control message: 'PUSH_REQUEST'
Jan  2 23:03:50 vpn-gw-int ovpn-server[12799]: brost.vpn.charite.de/87.185.222.132:1155 PUSH: Received control message: 'PUSH_REQUEST'
Jan  2 23:03:50 vpn-gw-int ovpn-server[12799]: brost.vpn.charite.de/87.185.222.132:1155 PUSH: Received control message: 'PUSH_REQUEST'

I almost seems as if the client is logging in multiple times.
Any idea what that could be?
