Do you expect this to affect both the testit run I tried (which seemed to
have got into a loop), and the original run with the Osi interface (which
does not appear to be in a loop)?

In the original run, where the problem is set up using the Osi interface
rather than reading from the MPS file, the code I am running alway
give bounds to variables -- it initially assigns -infinity to infinity (or
what getInfinity() returns) as bounds to the variable, and then adjust the
bounds for specific variable(s) if they are available. 

This is probably unusual for Mathematical Programming, where I think the
default bounds for variable is normally 0 to infinity. Could this be a
problem for the solving of l30?

Would you like me to generate the Osi calls for my run of the l30 problem
instance?
