Logs are repeated after archived

[FrontMage]

I have a 6 node process, they all use the same pm2 log config, streaming there log to the same file.

They are in cluster mode, but they were started separately.

Howerver, after pm2-logrotate archived these logs, every line repeats itself 6 times.

Logs for pm2-logrotate shows every archive has been created 6 times.

6|pm2-logr | "****err__2018-01-29-02-11.log" has been created
6|pm2-logr | "****err__2018-01-29-02-11.log" has been created
6|pm2-logr | "****err__2018-01-29-02-11.log" has been created
6|pm2-logr | "****err__2018-01-29-02-11.log" has been created
6|pm2-logr | "****err__2018-01-29-02-11.log" has been created
6|pm2-logr | "****err__2018-01-29-02-11.log" has been created

Therefore every time I tried to grep archived logs, everything repeats 6 times.

pm2-logrotate version 1.3.1
pm2 version 2.4.6
