Updating firewall rules in vapp times out

Hi,

We have several vApps with large firewall rule sett (700-1200 rules)  we normale update this with scripts, but some times it easier to add it manually throug the gui.  on the vApps with 700ish rules it works fine but with the largest ones the "updating network" fails with a timeout.  This always happens after 30minutes. So i guess there is a timeout limit configured somewhere in vCloud Director.

Any one have a solution to this or a suggestion for where to look?

Where using vCloud Director 5.5.3

thank you,

John
