Frequently logged out despite "Remember Me"

Website Win Chrome, happening in last few/couple weeks but not in couple years prior to that

Step 1: Log in as usual with Remember Me setting checked

Step 2: do a bunch of stuff such as IDing or annotating

Step 3: come back later, whether the next day or a few hours later- most of the time lately a fresh login is required

Is there some anti-spammer setting I’m triggering with high-volume activity? If so I’ll be happy to keep logging back in, but figured I should report in case it’s actually unintended behavior.
