[strongSwan] windows 7 cannot install eroute

[Luca Scamoni]

I'm using strongswan 4.4.1 on kernel 2.6.18-164.15.1.el5
clients connect using the following configuration

conn roadwarrior
        leftprotoport=17/1701
        right=%any
        rightprotoport=17/%any
        rightsubnet=vhost:%no,%priv
        keyingtries=3
        dpdaction=clear
        dpdtimeout=60
        dpddelay=5
        authby=rsasig
        auto=add

I'm having problems with windows 7 clients. If connection is terminated
abruptly (say, disconnecting the cable or closing the connection without
disconnecting before), further connection attempts from the same IP fail:

"roadwarrior"[298] <ipaddress>:4500 #10540: cannot install eroute -- it
is in use for "roadwarrior"[285] <ipaddress>:4500 #0

the only way to cure this behaviour seems restart....

is it a known bug? configuration problem? anyone else?

I browsed the archives but had no luck. anyone pointing me in the right
direction?
TIA
