Thanks, I investigated the code of new version udplogger. I understood
why it is not subject to the problems described above. Because it uses
one file for all clients. The old version tried to create a separate
file for each client.

Why you not using git hosting?
Old version is quickly searchable by google.
Look here it's second place in search results:

And new version is impossible to find in searching engine, it's so sad.
