Solman 7.1 Java stack not working after applying SPS 13

Hello,

We have applied the SPS 13 in our Solman 7.1.

The Abap stack seems to work ok.

But the java stack does not work (eg the sld is down).

When I connect through the icman, we have the following:

503 Service not available

Error is logged with Tag: {0001000f}

Could you please remind me in which log files I should look to diagnose my problem?

Thanks in advance for your answer.
