Have you attempted defaulting it?


If so, you are best off opening a support case- I have had my own personal ZD do basically the same thing and it ended in RMA.  Those two processes are experiencing crashes, and if you can't manage it there isn't much to do.

Yep, my way of fixing it has been to F/D it.. however you'd figure watchdog timer would execute some sort of script to recover from this

It seems like any time I am poking around with show commands in serial/ssh this ends up happening...

Show commands shouldn't cause that.  I know in my case I had done a few things that support didn't even know were features, but a power outage was the death bell for it.


Watchdog does try to recover, hence "is recovered from failure".  Unfortunately, there's only so much it can do if it keeps crashing.

I didn't do much other than set a management address on a different network than the IPv4 address

I initially was going to transition to a new subnet but was testing when this all happened, just seems weird

Yeah, that's nothing I haven't done several times, so it can't be directly due to that.  Out of curiosity, what model/software?  Do you know how long the unit has been in operation?

ZD3000 running 9.9.0, I was still bringing up some new APs on a different subnet issues with the zonedirector entry.. I had planned to go to 9.12 after I got them all online

According to support 9.9.1 is the highest recommended stable

I would suggest 9.9.1 as well, unless you need 9.12 for R710s.  The only other item I can think of is if this ZD has been through a large number of firmware revisions.  How long have you had this ZD?  3Ks have been supported since 7.0- do you remember what it was on before?

This is a new unit, literally unboxed last week... I've only REV'd it once from the previous version that falls within the upgrade path range it might have been 9.8 something (I cant remember the exact rev)

We've got R700s, would that merit the 9.12 code?

I actually noticed similar behavior on the same network but with a ZD1200, I am wondering if there are some underlying network issues, but I don't see how that would l cause the ZD to stop working

Only thing I can think of is this network runs DAI and I just managed to find a post about it causing issues with ZD

9.9.1 has more focus on the R700s (more fixes).  9.12 is the only code that supports the R710s, so at the moment if you have them you must run it. They tend to introduce new AP models with GA releases rather than MRs, and who knows if that new code comes with some new *ahem* "features"?  I'll take an MR over a GA any day, unless I need the features/support.

9.8 is fine- I was afraid you'd say you had it since 8.1 :) If it occurs again, it may be worth involving support.  They would have a better answer on the issues, or a different solution (maybe an RMA).  The ZD is new, but that doesn't necessarily mean that there isn't some issue with it.  It is exceedingly rare, but not impossible.

Don, Your message and description of reproduction events matches an issue ZF-11690: sqlitedTac.socket crash, in our bug database.

Found on version 9.10,

Steps:


1.Set ZD to factory configuration


2.Changed ZD's vlan to vlan10


3.ZD restarted and did some basic configuration


4.sqlitedTac.socket crashed.----issue



I've added a comment that you hit this too.  If you could please open a Tech Support ticket,

reference this ZF-11690 issue, and we will see that you get a firmware update with a fix.

(when one becomes available/released)

This issue seems to have gone away -for now- after we added an exclusion to the webfilter for ZoneDirector IP addresses

I have a feeling that if ZoneDirector cant 'call home' something crashes and causes this behavior.. Every device on this specific network goes through a Lightspeed web filter

I also upgraded to 9.9.1 from 9.9.0 so I am not excatly sure what fixed it
