Client resumes session repeatedly every minute?!

one of my app’s users is causing a new log entry, "Resume login", about every minute or so.

Does anybody have any idea what could cause such behavior?

It looks like a normal resumed session, but it’s happening non-stop, day and night, with an interval of 1-3 minutes.

I can easily ask the user questions about this issue, but I can’t think of anything to ask :confused: “Are you by any chance reloading your page in a very neurotic manner?”

"logindata": {
            "type": "resume",
            "allowed": true,
            "methodName": "login",
            "methodArguments": [
                    "resume": "secret resume token"

and the client’s user agent:

"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.79 Safari/537.36 Edge/14.14393"
