The problem with this assert still exists.

Original source from B3_0_Release, FB 3.0.2.32629, x64, VS2015 build, SuperServer.

1. Connect to database
2. Disconnect to database
3. Wait one minute
- server unmaps the "fb_lock_xxxx" and "fb12_monitor_xxxx" files
4. Wait one minute
- server unmaps the "fb12_trace" file
5. Try to connect to database and get this problem

With release build (in same scenario - connect/disconnect/pause/connect) I get the "Error occurred during login, please check server firebird.log for details." error.

Tested at FB x64 SuperServer (VS2015 SP3 build).

This problem is still existing in FB 3.0.8.33540 SS Win64.

This assert was happened when a couple of explicit garbage collectors (gfix.exe) for different databases were started by scheduler.

These gfix.exe connect to server through TCP/IP.

I know that this version of server is outdated.
