[Openswan Users] 2.6.24rc1 (klips) UDP 500 Port not released after unloading ipsec module

[Sven Schiwek]

Hi,

I'm currently testing 2.6.24rc1 (klips) on Linux Kernel 2.6.30.9.  
After some days and some Openswan restarts "netstat" shows some open  
UDP 500 Ports (more then 10). To resolve this issue I stopped Openswan  
and unloaded the ipsec module but the port is still in use.

Every time I start Openswan a new UDP 500 port is opened -  
interestingly, the VPN works. Attached you'll find some shell output.  
The first time I unloaded the ipsec module the Kernel crashes but  
unfortunately after the restart I can't reproduce this crash (crash  
attached). I will try to recrash the kernel and analyze the situation...

I hope someone can help. Thanks
Sven
