Ah yes crossed wires here! I thought that there was a 'researchable' menu area that I was missing. Your technique can only apply if Limewire is left running for several days with no more than 8 search tabs active.
I use the resume button under 'Library'-'Incomplete ' in any attempt to reactivate a connection.

Unfortunately I've never had Limewire run for more than a day without hanging/requiring a restart.
In point of fact I 'blame' L/Wire for causing Kernal panics.
If left running overnight I almost invariably rise to the dreaded 'Restart message'
