Mystcraft link book crashes

[Shevron]

Anyone else having their client randomly derp out when using Mystcraft link books?

Seems to be fine right after logging in, but spend some time on MC, and next time anyone uses a link book, everything goes dead.

Looks like a network problem. I have other problems when using link books:

With much effort I tracked it down to a ComputerCraft monitor.
