I've run into a issue where firewall locked up and crashed because of a high number of sessions (Firewall-1 v3.1 on Solaris 2.5). I've recently run into an Intranet FW issue where SunRPC session ttl value (across the firewall) was set to 12hrs, and the firewall locked up & crashed after 6 hours (Network-1 on NT). I've heard a unsubstantiated rumour (customer says Network-1 tech support told him) that file transfers >1.3GB across an NT firewall will cause it to lock & crash. NT addresses up to 4GB virtual memory, allocates 2GB to applications and 2GB to the O.S.. All are memory related, specifically the firewalls run out of virtual memory. All are on packet-filter firewalls, not proxies. Is running out of virtual memory a well known problem or new? Is this a 32-bit/packet filter issue only? Bill Stout
