[foxboro] IA Batch problems

System specs: AW51B, IA ver 6.3, IA Batch ver 5.3 with 4 batch trains
The Story: 
At about 0400 Saturday morning, IA Batch locked up and would not step through 
the recipes. Found that /opt partition was 100% full. This is due to it being 
full of batch history files. So... I deleted some of the larger H01*.dat files 
and H02*.dat files. Got /opt down to 87% full. Then restarted IA Batch.
Upon restart, Batch does not allocate equipment in one of the trains, but works 
fine in the other three. In the batch display, it states "waiting on phase 
status", the phase is idle, and has the correct codes to show that it is 
available.  I called TAC at around 1900 and was told that erasing the H01*.dat 
files was the cause, I didn't believe this, but it was possible, the problem 
train was the first installed,  I'll try anything to get the system back up and 
running. So yesterday I spent most of the day, restoring the entire hard drive 
from a backup tape made in Sept. which has the /opt partition at 99% full. Then 
restarted Batch, and I still have the same problems.

So some how my phases and batch have lost connectivity, does anyone have any 
idea what I can do to resolve this? I looked through the IALink files, and 
cannot see any differences between the trains that work, and the one that does 
not. 

Also, does anyone know if those HO*.dat files can be removed?  I have history 
files going back to 2001, I only need to keep about 6 months worth.
