How'd it go? Any glaring issues? I'm looking to upgrade tonight

Sorry, I was already gone for the day when I saw your message. I haven't seen any new problems, and I have not seen the SSL freeze, but like I said in an earlier post our load is really low right now.

Upgraded yesterday from 7.0.3 to 7.0.4 (3 firewalls), no issues so far. SSL freeze seemes to be fixed.

And also the annoying bug  that some Microsoft sites failed to load randomly.


This is the first time that i am satisfied with the 7.0.x release.

It looks finally "production ready"

Yeah I have the same experience. I upgraded one set of 3050s last night and so far things look good. I noticed they increased the FPTCP buffer from 32768 to 131072... quite the jump! I monitor this value every 5 seconds and I've yet to see the buffer go under 129000, whereas before it would hit 0 quite often (and thus cause the decryption outage). I'll continue to keep an eye on it and will report here if things go south again.

So far no issues in a week. I'd say this bug is squashed finally.

Here also, no issues after a week.

I agree bug squashed!

Hi Guys,


We are planning on upgrading to 7.0.4 in a couple of days, has anyone upgraded yet and if so was your decryption issues resolved.

I upgraded on Sunday afternoon and so far so good.

@sokonta  (Says the 4 or so other people before you saying they haven't seen the bug they previously saw in 7.0.3 with SSL enabled.)
