Background
Both supervisor and pm2 write logs to /var/traveloka/logs/ there is a possible race condition when app still write to file and supervisor rename the log from service.logto service.log.1App doesn't care about it and keep writing to service.log.1. Reference
Fix
This should be fixed after adding copytruncateto logrotate. If this happened to your service, it should be fixed after next deployment from commit 70dad8a16fcecece3fd1fa167c4547fd805b557b
