[CentOS] strange system outage

I have a CentOS 7 system that I run a home grown python daemon on. I
run this same daemon on many other systems without any incident. On
this one system the daemon seems to die or be killed every day around
3:30am. There is nothing it its log or any system logs that tell me
why it dies. However in /var/log/messages every day I see something
like this:

May 10 03:35:58 localhost pure-ftpd: (tool at xx.xx.xx.xx) [NOTICE]
/usrMay 10 03:57:57 localhost pure-ftpd: (tool at xx.xx.xx.xx) [NOTICE]
uploaded  (90666 bytes, 8322.34KB/sec)

Notice how the message that was being printed at 03:35:58 is truncated
mid-message and the next message is at 03:57:57 – there are always
messages like around the time when the daemon dies. What could be
going on here?
