Symptoms

SmartView Monitor "Top QoS Rules" view shows that almost all traffic matches the "No Match" rule.
Example:
Kernel debug ('fw ctl debug -m RTM + rtm view_add per_conn') on Security Gateway shows that sometimes SmartView Monitor fails to read the QoS rule.

Examples:
- ;svmClassifyKviews : [first time] Conn: =<[192.168.0.141(c0a8008d) 192.168.1.1(c0a80101)] [65054 53] [17]> cl_in: 1, cl_out: -1, s_in: -1, s_out: -1; ;get_fg_matched_rules: Get rule for ifn 1, dir: 0; ;get_fg_matched_rules: The ifn:1 is not active. (direction 0); ;svmClassifyKviews : could not read matched rule from FloodGate;
- ;svmClassifyKviews : [mismatch] Conn: <[192.168.0.141(c0a8008d) 192.168.1.1(c0a80101)] [65054 53] [17]>; ;get_fg_matched_rules: Get rule for ifn 3, dir: 1; ;get_fg_matched_rules: The ifn:3 is not active. (direction 1); ;svmClassifyKviews : could not read matched rule from FloodGate;
In addition, whenever a new SmartView Monitor view is opened, the connections are re-classified, which causes "no-match" for a short moment.
Disabling SecureXL resolves the issue.

Cause

When SecureXL is enabled, interface information is saved in advance also for the other direction (in case the connection will be accelerated - i.e., if packet is 'Client-to-Server', then the same interface is saved for 'Server-to-Client' direction).

However, since interface information is saved, an interface mismatch can not occur. As a result, a QoS rule is not reclassified (which is per direction, unlike in FireWall rules) for the other direction.
