Not all info dumped into console. You need have both, for track and solve different kind of problems.
For fix this, you need specify
log=server.logsomewhere in ucc.init config, for sent it as param to ucc.
Log appear as server.log in your System dir. If you want use Logs dir:
There example how do that:

Optionally you can make some renaming some where in ucc.init for store not only last server.log, but last few.
Or you can make it date based via bash power. Be sure it not flood your entire server with logs.
AFAIK ucc.init come from ASU: https://github.com/abfackeln/ut/
So possible it can be patched here, so all who use it can use it with proper logs.
