- Firebird 3.0.3.32802 x64 (SuperServer)
- Connection through TCP/IP (localhost)

Server has entered in infinite loop(?) in one own thread (ID: 24436)

I waited 24 hours.

At client side (multithreaded test system) all test threads wait the answer from server:
- 1 thread wait answer for COMMIT_TR
- 3 threads wait answers for START_TR
- 7 threads wait answers for DETACH_DB

Sources, dumps, binaries ...: http://dropmefiles.com/h0au4 (valid within 14 days)

// See if the lock already exists
