I have a very strange problem.

We use iFolder 2.1.3 on a NW 6.5 SP2 with client 2.1.3 (yes I know it's
ancient), and the problem is that for some users the iFolder seems synced,
but for some reason the client (or server) stops syncing their account, but
the client reports that it is logged in and has synced. (yellow map with a
red 'i')

What could be the problem?
Is this a known problem that is fixed in a patch? I've searched but I
haven't found anything that looks like a fix for this problem.

This is a big problem for us because we cannot trust iFolder until this is
