[SOLVED] Calibre DRC error exporting layout

[The_Dutchman]

Hello all,

I have a strange problem running DRC check using calibre. When I start Virtuoso, license "111" is succesfully checked out and everything works fine (Schematic, Layout, MMSIM).
I implemented the Calibre skill interface in the .cdsinit and the drop down menu in layout editor appears. When I start calibre from within the layout editor drop down, the calibre gui pops up and the calibre-interactive license is succesfully checked out.
However when I then try to run the Calibre DRC somehow it tries to check the Virtuoso "111" license and fails prompting the error message below (things go bad during export I think):

//  Calibre layout-server initialized successfully at socket 9199, host Somehost.localdomain.

*Error* License "111" could not be checked out.

ERROR (XSTRM-209): Virtuoso Framework License (111) could not be found. Either the license server is down or the license is not available. Ensure that the valid license is available.
INFO (XSTRM-273): Translation failed. '1' error(s) and '0' warning(s) found.

I am sure that license 111 is available because else Virtuoso would not run. The warnings can be neglected (everything runs fine, I think it is missing the /etc/redhat-release to be a known supported configuration).

Status of the license servers is given below, the servers are up and if I check the log files all feautures are found and the deamons are running:

Any ideas of what I can try or check?

Thanks

EDIT: The error is not Calibre related. I tried to do a DRC check with a exported layout stream.
I get the exact same error when I try to export the stream using Virtuoso -> export -> stream.

EDIT: All was solved relatively quickly by patching the long signatures in the license files.
