ASA Firepower stops forwarding traffic

[faizan.khan]

ASA Firepower software module stops forwarding traffic and i can't see anything in any logs
That could cause this problem.

If we redeploy policy's without any changes it starts work again !!!

Installed ASA Firepower version/files
asasfr-sys-6.2.0-362.pkg
asasfr-5500x-boot-6.2.0-2.img
Cisco Adaptive Security Appliance Software Version 9.8(1)
Firepower Extensible Operating System Version 2.2(1.47)
Device Manager Version 7.8(1)

Any idea what this problem can have for causes ???

I would suggest to open a TAC case for the sfr, did you check if the module is crashing??

Open a ticket with TAC
