FCB ageout in SRX550
« on: April 13, 2015, 06:24:25 am »
Hi all,


I have a customer with SRX550 cluster on which we are noticing a lot of the following logs:

RT_FLOW: FLOW_REASSEMBLE_FAIL: FCB ageout before all fragments arrive .........


This appears to be causing login problems for our clients on remote sites, but before I can tell for sure, I would like to know more about the FCB.
Online documentation is scarse at best, but I understand that packets get split in 100-byte packets, and then reassembled. If that doesn't work within the age-out of 3 seconds, the packet gets dropped.

Does anyone have more experience with this kind of problems or know how to solve them?
I know that on SSG you could alter some setting related to FCB pool, but I can't find a similar option for SRX


regards

amccully
