[strongSwan] Slow script called by leftupdown causes clients to fail connection

[flyingrhino]

Hi,

I've got a script on the responder that is called upon client 
connect/disconnect via leftupdown.
Normally this script exits within 1-2 seconds, but sometimes it takes 
much longer.

Strongswan waits for the script to exit before continuing the connection 
process, which can cause a connection fail if my script takes too long.

I tried forking the slow functions in my script, but it appears that 
strongswan waits for them to exit too :(

Is there any way I can tell strongswan not to wait for forked processes 
to exit (only wait for the main process called by leftupdown)?

Or possibly, can you recommend how to create a new process (from the 
leftupdown script) that strongswan won't wait for to exit?

Thanks.
