Yes, specifically the publication in socialize:user-presence is being stopped and started repeatedly.
Meteor.publish(null, function userPresenceSessionConnected() {
if (this.userId && this.connection && this.connection.id) {
userConnected(this.connection.id, this.userId, ServerPresence.serverId(), this.connection);
sessionConnected(this.connection);
this.onStop(() => {
userDisconnected(this.connection.id, this.userId, this.connection);
sessionDisconnected(this.connection);
});
}
this.ready();
}, { is_auto: true });
