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: https://imgur.com/a/IKHY8 And new version is impossible to find in searching engine, it's so sad. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
