[si netlister] not running, but no useful error message

Hi all,

I'm running the "si" netlsiter and It's saying that I have successfully checked out the license and what the value of some timeout is.

% si -batch -command si.cmd -cdslib ../../cds.lib
Virtuoso Framework License (111) was checked out successfully. Total checkout time was 0.03s.
INFO (DB-120008): oaSocket connection timeout value was set to 2 seconds.

There is no other output. The only thing that gets written in my run directory is a file "si.env" which echos most of the commands from my si.cmd input file.

I doubt it's related to the content of my command file because I've also tried to run with a subset of the commands and even with an empty command file, but the message on the screen is always the same.

Any ideas how to debug this further? -- Thanks!
