smake only shows output of one sc call about amitools

[titanlab]

Also, if I compile a lot of files from the SMakefile (I now have around ~30 phxass calls and ~40 sc calls), I get the following error:

If I manually increase the number of slots to 2048 in the LockManager, it's fine. Any idea how I can analyze/fix that?
