Since I updated my NodeBB to the latest 0.7.0 version I've noticed that my "sessions" collection keeps increasing in size constantly, like if the sessions in it were never expiring and always being re-created. I'm experiencing this issue only with Openshift, while my instance in AWS Elasticbeanstalk is working just fine. Not sure if this info is relevant though, because in the Openshift instance I did some changes in NodeBB, like new routes and other node modules, but I haven't tested yet if they are the cause of this issue. In any case, if I just drop the "sessions" collection, it will show like 50 new empty sessions in less than 10 seconds. Some documents: { "_id": "pmJRsePD-ctzSQ0rtzW49k-KohSs2WHp", "session": "{\"cookie\":{\"originalMaxAge\":1209600000,\"expires\":\"2015-06-16T13:38:19.835Z\",\"httpOnly\":true,\"path\":\"/\"},\"passport\":{},\"csrfSecret\":\"F5RHBIVPiK9QyDhiE4iXWP_B\"}", "expires": { "$date": "2015-06-16T13:38:19.835Z" } } { "_id": "oqDkaZfvoY_J0b-iNe0pyzrKufeTHEjD", "session": "{\"cookie\":{\"originalMaxAge\":1209600000,\"expires\":\"2015-06-16T13:38:19.984Z\",\"httpOnly\":true,\"path\":\"/\"},\"passport\":{},\"csrfSecret\":\"smJWt0HbwNY9QSGTpr0w2wDx\"}", "expires": { "$date": "2015-06-16T13:38:19.984Z" } } { "_id": "14qrP1DtX3Qr2bbchAM4tcKIg3Uu9CnE", "session": "{\"cookie\":{\"originalMaxAge\":1209600000,\"expires\":\"2015-06-16T13:38:20.281Z\",\"httpOnly\":true,\"path\":\"/\"},\"passport\":{},\"csrfSecret\":\"WJhAT0xS5cQcL4lTU7kz3Qar\"}", "expires": { "$date": "2015-06-16T13:38:20.281Z" } } The closest thing that I could find on the web was this post which somewhat describes the issue I'm having, but I'm not sure if it's really related. Any help on this matter? Regards!
