[Openswan Users] windows client fails to rekey

[Marc Fisher]

Hello,
I've had this issue since I started using openswan. In short, the 
windows client disconnect every 60 minutes, due to failed rekey process. 
I'm simply using the windows "redial on disconnect" option to keep the 
line up. I have to, however, restart ipsec every few days, because 
openswan connections start to pile up to hundreds, and it actually 
crashes the linux server after a while. I've been waiting for few new 
releases before writing here, but since the problem presist in 2.6.27, 
I'd really appreciate any advice into what is causing this. I'd also be 
very interested to hear from someone who is not experiencing this issue 
- his/her windows xp machine rekeys successfully.

This is how the connection drops after 60 minutes:

First I though the line
netlink recvfrom() of response to our XFRM_MSG_DELPOLICY message for 
policy eroute_connection delete was too long: 100 > 36
was to blame, so I applied the patch from 
https://gsoc.xelerance.com/issues/1120
It doesn't help unfortunately, now the process looks like this:

Is it normal that the client sends " Delete SA" during rekey? Is windows 
messing up here?

My barf is here: http://ioudas.net/openswan_barf.txt

I'd really appreciate any ideas as to what might be causing it, even if 
the idea doesn't include solution :)

Thanks,
Marc
