Application Crash on FGT100D with 5.2.5

[HA]

Hello,

After upgrading two fortigate devices (not in cluster) with release 5.2.5, Application crashes appears now in the log.

Pid: 00938, application: , Firmware: FortiGate-100D v5.2.5,build0701b701,151203 (GA) (Release), Signal 6 received, Backtrace: [0x2a95c54c4b]

After doing some research, it appears to be related to proxyworker process.

Only Fortigate with UTM features enables faces this issue...

Downgrading to 5.2.3 ??

Regards,

HA
