No, it shouldn't.  Sites disconnect and reconnect all the time without
causing trouble.

I guess I should clarify my original comment about what WSI is running. 
I think I said they had modified a version of the LDM, but I found a
recent quote from Charlie O'Brian at WSI in our archives:

In thinking about this further, I'm not sure I'll be able to reproduce
this problem after all.  We do not have a COMPAQ machine available.  Is
that the Alpha 64bit chip?  Do you know if you can build both 32bit and
64bit versions of software?  I'm wondering if you built a 64bit version
by default, and if so, what would happen if you built a 32bit version? 
If you could possibly perform this test, it might be revealing.

We can build 64bit versions of the LDM on our SPARCv9 or IRIX64
machines.  If I here from you that you're running a 64bit version, I
will do this and request WSI data and see what happens.
