openvpn produziert Zombies synoautoblock + synovpnlog

[brutusalem]

Hallo,

nach jeder (erfolgreichen) Verbindung von einem Windows-PC (Win7 32) auf
meine Synology DS212+ einsteht ein neuer synoautoblock-Zombie, ausserdem
genau ein synovpnlog-Zombie.

root ~ $ ps | grep 'Z'
13906 root 0 Z [synoautoblock]
14368 root 0 Z [synoautoblock]
14731 root 0 Z [synoautoblock]
15399 root 0 Z [synovpnlog]
15679 root 2988 S grep Z

Wird auf der Syslogy der openvpn-Server gestoppt und neu gestartet, sind die
Zombie-Prozesse weg.

Hat irgendwer eine Idee, woran das Problem liegt?
Bin für jeden Ansatz dankbar.
