5.6 System Events - Virtual WAN Link volume status

[bcote]

Hi guys,

I am having consistent logs every 5-10 minutes : 

10:13:34 The member(1) stops receiving new sessions for too much traffic.          Virtual WAN Link volume status

10:13:34 The member(1)resume receiving new sessions for internal adjustment.   Virtual WAN Link volume status

I am using SD-WAN with a single connection right now(1Gbps) as the 2nd connection is still being installed by the ISP. Is this something to be concerned about? Could it be simply since the SD-WAN only has 1 connection? I am definitely not reaching my 1Gbps limit as this is very slow times and I barely use 200Mbps. 

Any indication on what this means would be greatly appreciated.

Hi Dustin,

sadly nothing yet. I was waiting for 5.6.1 to come out, which from what I heard, should be in the coming days/weeks and see if that is fixed. I am actually adding my 2nd ISP link to the SD-WAN tomorrow and will see if the message is still present afterwards. I was suspecting the logs were possibly false/positive, but I won't know until I do some changes and hopefully, if it is a bug, when 5.6.1 comes out, it will be addressed. 

I'll keep you updated.

FortiOS 5.6.1 was released yesterday.

[bcote]

oh yeah. I have been looking daily, but seeing as it was released around 4 pm yesterday, I missed it this morning. I'll be testing it out this weekend either way. From what the release notes are showing me, I don't see much affecting my configuration, and since we are a smaller shop... and I love bleeding edge, it'll be in before Monday.

I'll let you know if the logging issue is resolved on this version

Hey Dustin,

Completed the upgrade to 5.6.1 without any issues. Added my secondary ISP to the SD-WAN link. Everything seems to work fine. They are both weighed 50/50 and I see traffic flowing through both, but as far as the logs go, I still still every 5 minutes the same logs over and over, from both lines now. I will open a ticket with Fortinet as I want to be sure this isn't an indication of another issue.

That's just the log from where it is balancing based on volume. Your load balancing should be working without issues
