Hi Andrii, this final release has a difference with the 5.9.2rc5?

@Alessio_Garavano

this final release has a difference with the 5.9.2rc5?

That’s my question also – is there any difference from 5.9.2-RC5, or was RC5 determined to be stable, and this IS that candidate, just renamed? I have a couple RC5 sectors & their SMs (which seem to be doing well) but just wondering if I should bother moving them to 5.9.2 Release version, or if they actually aleady are on the Release Version anyway.

[Fedor]

It’s 5.9.2-RC5 released as the final version.

Thank you.

When will the ping problems in PTP mode on the 4625 be fixed?

Or is there any chance of improvement?

[Eric_Ozrelic]

What ping problems are you talking about?

[Mustafa_Spz]

When the real traffic exceeds 500 Mbps, the devices start to apply a timeout error.

There is the same problem with PTP 4625 features in 8 different locations.

[Jacob_Turner]

Are you pinging the radio or something on the other end of the link that is not a radio?

[Mustafa_Spz]

This is a direct ping to the radio.

Anyone using Cambium 4625 as PTP and passing 500 Mbps traffic knows this problem.

[Alessio_Garavano (Galeno)]

Try to downgrade to the last recommended version 5.9.0, we are downgrading all our network to this version with better results and no downlinks or timeouts. At now this is best version, at least for us…
Regards!

[Mustafa_Spz]

We used 5.9.0 for a long time, the situation was the same in that version.

I think there is a chronic problem.

[madmax123]

I solved the problem like this
config set cambiumAccelerationEngine 3
config commit
reboot

[SBBinc]

Same here.
Once this fix was applied, no more weird issues.

Whoa, check your CPU stats everyone!!!

I upgraded a few towers early this morning and ALL of them had huge increases of CPU use.

An example was one epmp3000 with only 12 subs went from 13% to 61%!!!

This is wild and cannot be expected. I imagine theres new features, but i have not turned on any packet inspection stuff and ALL APs and ALL SMs have had these massive jumps in CPU use.

I will be reverting back

[Eric_Ozrelic]

We’ve updated our entire network of e1/e3k/e4k… hundreds of radios and have not experienced that with 5.9.2. So I’m wondering if there’s something different in our configurations?

Second… are you sure that the extra CPU usage is causing an issue? Even if I was experiencing unusually high CPU usage, unless it was impacting traffic, I’d leave it on 5.9.2 and work with support to help identify the issue. It may all just be a superficial reporting issue.

[riddle]

It doesn’t look to have effected traffic. I can still get 370Mbps to a cpe router. Pretty horrible to see a jump that high though, and on ALL APs and CPE radios put on 5.9.2. Its a shame too as I’ve seen some modulation stability improvements. Probably a good idea to open a ticket and work through it though.

[riddle]

Looks like this … from 3:30AM so no traffic passing

Yuck

[riddle]

update: disabling crash reporting is the fix. They know about it and 5.10 will fix. Unsure if a beta will come sooner.
