Smartzone 100 and R730 Reboots/ Offline Issue

[kevin_7278725]

Is anyone having issues with R730's randomly going Offline and requiring the AP to be rebooted in order to get it back online?  We have been seeing this issue for about 30 days now and support has been unable to tell us why the R730's are doing this.  The AP's are inaccessible most of the time when the issue happens, but sometimes we are able to still ping the AP and actually SSH to the login prompt, but the admin account/password will fail.  Once we power cycle the AP it works fine again.   When the issue is happening the AP is still accepting clients but it has no network access so those clients are broken.  It is very frustrating and Ruckus support has been no help.  The R730's are connected to Ruckus ICX 7650's via 5Gb multigig ports.  The switches report no problems and there are other AP's on the same switch at the time that have no issue, so the problem is just random Access Point specific.  The issue is completely random, no pattern can be found, other than support telling us they are seeing AP kernel panics and that they can't tell us why or how to make stop.   

Smartzone 100 version is 5.1.2.0.302 - which support had us upgrade to as they said that would fix the kernel panics - It has not

R730 version -  5.1.2.0.373

A few of the R730's have not been able to recover from this issue after a reboot and have had to be RMA'd.  Some of them will automatically reboot after 15-30 mins, but if we manually reboot them they typically come back online and work.  Was curious if any else is experiencing this issue with R730's, Smartzone 100's, and ICX 7650's?

@Kevin, have you triple checked the power issues? https://forums.ruckuswireless.com/ruckuswireless/topics/high-drops-and-retries-on-r730

We using Cisco SG350X PoE+ switches - and of course all APs and the ports are set to provide at+ power. But its explicitly NOT UPoE or similar 60W standard on that ports.

Yes and it would be really sad if it was a power issue considering we have all our R730's connected to Ruckus ICX 7650-48ZP's.  The engineering team at Ruckus believes 5.2 will resolve some of our R730 issues but the kernel panics that appear to be a Qualcomm chipset issue it will not.   We provided new custom debug logs this week and hope they help them find the root cause of the issue.   We still have R730's randomly reboot and or hang and then reboot multiple times per day.  There is no pattern that can be located currently.

@Kevin: Do you have any update from our side regarding the R730?

[kevin_7278725]

The original 5.2 release was pulled as it was bricking some model AP's (supposedly not the R730) so we waited.  Ruckus provided us a custom 5.2.x build last week and do to scheduling we are looking at implementing on March 16, 2020.   I will update this post later next week but with everyone working remotely I am not sure we will experience all the same issues until we are back under full load.

Just wanted to add that we are experiencing the "R730 - AP Hangs and no longer works. It reboots itself after 30 mins" issue too. But we use Ruckus Cloud and
Ruckus ICX7150-48Z switches instead of Smartzone.
