Sessions Not Closing

[travis_1983]

Hi guys,I have a case logged but maybe someone here can help.Since upgrading our firmware two versions up - both versions appear to be resulting in extremely high session count, slowly rising to 6000000 - resulting in loss of service.FG 500E - Firmwarev6.2.1 build0932 (GA)Support have only recently escalated the case.At the moment we're closing sessions via CLI to keep our device up. It the 'CLOSE state' which keeps rising. diag sys session statmisc info: session_count=2873174 setup_rate=91 exp_count=883 clash=0
