i recently upgraded lucee and switched to the lucee redis extension. (i had been using a third-party redis extension.) we use redis for lucee session sharing and for some mura caches. i've gotten some complaints about "early logouts," which might be related to the session persistence (across the lucee cluster). i'm also getting a lot of this in the logs after pushing
