Don't confuse AppleShare and HFS. Volume size limits in one will not necessarily apply to the other. Pre System 7.5 Macs, for example, can access AppleShares much bigger than 4GB.
System 6 uses AppleShare Client 2.x, which may have AFP (AppleTalk Filing Protocol) volume size limits. I have done more testing on AppleShare, using loads of clients (Macs, Apple IIs, PCs), and different servers (AppleShare, NetWare, NT) than any one else. My testing was based on typical shares in the 1990s. Possibly naiive.
You may have hit an AFP volume or file handle limit. Let me know the nature of your working network environment. If the scenario is realistic, I'll test again.
