APs rebooting due to adoption timeout E2122 appliances

[froggy]

Hello,

All the APs in one of our sites were rebooting due to adoption timeout. The poll timeout was set to the default (3 seconds). We rebooted the APs and that seems to have fixed it but we have seen this messages before on some APs. I changed the poll timeout to 60 seconds on that site but I'm wondering if there is other settings or issues causing this. Today this was the only site experiencing this. we have a total of 1500+ APs with two E2122 active active pair

Hello @froggy,

With 1500 APs at stake, I'd suggest you contact GTAC and have a dedicated engineer work with you on this issue.

so after talking to GTAC they told me these are normal messages if the APs lose tunnel connectivity to the controllers. After investigating a little bit more i found that we had some type of network outage at the locations where these APs are located. No one reported it because they happened after ours or before. this is the first time i actually saw this messages and i thought it was random. So far it looks like all of the APs that rebooted this way have a correlation to a network outage.
