potential FortiOS 6.0.9 memory leak

[Ray]

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 

6.0.9:

PID RSS CPU% ^MEM% FDS TIME+ NAME * 208 1G 0.0 17.6 637 34:16.79 ipsmonitor [x9] 202 353M 0.0 4.4 64 38:45.62 miglogd [x5] 231 82M 0.0 1.0 31 11:46.27 dnsproxy 205 67M 0.0 0.8 23 00:56.10 httpsd [x4] 180 42M 0.0 0.5 14 00:30.36 cmdbsvr

Do you have the same issue?

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.
