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@xx.xx.xx.xx) [NOTICE] /usrMay 10 03:57:57 localhost pure-ftpd: (tool@xx.xx.xx.xx) [NOTICE] /usr/local/motor/data//B31/today/Images/CP0982436.00C_T6PH8_M0-R_1/T6PH8_M0-RN_TT6PH8_M0-R_P4_M1_FX-1_FY4_RR1_TR1_Ver3.jpg 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?
