When running trace from fbsvcmgr sometimes (rather rarely) it fails with error message:

Unknown tag (0) in isc_svc_query() results

Commits: 2a75646 a4e79bb 422f382

====== Test Details ======

First time it was found in LI-V2.5.8.27072 and 2.5.9.27117. Number of attachments did not matter but trace .conf must contain almost all options with include status = true.
Discussed with Vlad and Alex since 13.12.2017; resumed 19.09.2018; 20.11.2018; 23.11.2018 (catched additional debug info, got explanations from Alex); 11.02.2019.

Bug can not be reproduced in normal time: at least 25 minutes required for this, without 100% warranty that this error occurs.
