Windows task manager I seen very low memory usage (0.4MB) and on Linux
I see next: https://snag.gy/ban3jX.jpg (i am not familiar with Linux
and do not sure if process is alive or not because htop do not show it)
The code is *very* simple https://github.com/bubnenkoff/dlang.ru
Is there any ideas how to diagnostic the problem?
I got error https://paste.ofcode.org/exCL5S2vbp6qhYBqj7v6ez
Is it's issue with libevent?
Does even-loop depend on used OS?
The dpaste shown doesn't seem to match the code in the repository. There
is a reference to vibe.web.rest and the mysql-native driver, which I
couldn't find in the dlang.ru source code.
The error is most likely caused by issuing two requests to the MySQL
server from two different tasks on the same connection. Usually,
mysql-native uses a connection pool to avoid this, but that could have
been circumvented by accident.
