potential FortiOS 6.0.9 memory leak

We reverted FortiOS 6.0.9 back to 6.0.8 after nine days, because memory usage went up from 41% to 46% and kept growing.
At cli, "diag sys top-summary '-n 5 --sort=mem' " showed

    Hello,
     
    Yes, by monitoring with diag sys top-summary, I see that it is the process "ipsmonitor" which consumes more and more memory...
     
    Since the IPS engine update (4.052 to 4.058) the memory was stable.
     
    Contact Support Fortinet for new IPS engine.

    Cluster Active/Passive Fortigate-1500D 6.0.9 (AV, DLP, AppCtrl & IPS, DHCP, AlertMail, Fortiguard Web & AS, OSPF & RIPv2, SSL-VPN Portal Web and Tunnel)
    FortiAnalyzer-3000D 6.0.8 (Log, Syslog, Alert event, Quarantine & Report)
