We are seeing intermittent reboots of APs with this message showing in ZD as the restart reason. What is the cause of this?

Hello Andrew,

The reason Target fail detected indicates a software crash but to know the exact reason we would need to extract dram dump from the AP. The dram dump can be taken from AP shell and hence restricted to Ruckus support. Kindly open a case with Ruckus support to collect the logs and provide a resolution.

We are having this same issue. We have 15 - 20 AP in the field and we seen this 3 times in the last 4 months. We discovered if you change the AP (master to slave) and back it seems to fix this issue temporarily. If that doesn't work you need to reset the AP and start over.

Hello Tom,

Kindly open a case with Ruckus support as to identify the root cause for target fail "dram dump" needs to be taken from the problematic AP. Once these logs are collected then root cause would be found.

Hello Tom,

The case#00877649 was closed as no contact since there was no response on the case. We will open a new case and and engineer would assist you ahead, also I would suggest to upgrade the Unleash network to the latest available version which is 200.7 and monitor the behavior. Below is the image for R310 Unleash AP.

Hello Janx,

The case has been opened with contact name as Hannes Mulla and preferred contact method as email so the case engineer has been following up on the case through email to [email protected]. Till now there has been no response to the engineer and hence case is in "customer pending". Please call support (https://support.ruckuswireless.com/contact-us) and mention the case number 00916556 or if the case has been opened with your account you can access the case and update through https://support.ruckuswireless.com//cases/00916556 or please confirm that you would require a call back on +372 650 9381 and need email to be added as [email protected].

The engineer would require support log of the AP's that are rebooting along with the controller debug log.

Best Regards
Vineet
