ASA5510/SSG520 VPN Phase1 renegotiation problem


I have a problem with multiple VPN tunnels that I cannot figure out.

I have a IPSEC site-to-site vpn between a Cisco ASA5510 and a Juniper SSG520.

The VPN is up and running as expected exept when Phase 1 needs to be renegotiated.

When that happends (Every 24 hour) the Citrix clients looses connection to the Citrix server and the Outlook clients are reporting "Offline" I have setup some ping jobs that shows that only 1 packet is lost during the Phase 1 renegotiation.

The users can connect to the servers afterwards without any problems but they are anoyed by this.

I have updated both firewalls to the newest firmware release without any luck.

Anyone have a clue as to how to get this fixed.

Hope someone can shed some light on this.
