LJ blarghage

I've been having a recurring issue with LJ for a while now, and I cant seem to pin it down. While perusing my flist I will occasionally will have it missing everyone's locked entries. It's as if I intermittently lose the login cookie. Or something. I can reload the page and the missing entries reappear. I have to be mindful of this as I try to catch up or I will miss out on those locked entries. This happens on more than one PC here as well. Is this something that anyone else has been experiencing on a regular basis?
