Hi everyone. Relative NOOB with OMV and Linux, but I work in IT and am pretty fluent with Windows (I've worked in IT helpdesk/desktop for the last 2 years)
My problem: During a long copy of files/directories from a Windows 7 PC (about 800GB), OMV crashed at nearly the 13 hour mark. Shares went offline, and the box turned off completely. I'm baffled, and sorta concerned for its stability after this. No issues have been observed previously.
Specs:
OMV 5.3.2.1 (which I just updated after the crash to 5.3.4.1)
Intel i5-3570
16GB RAM
AMD-64 Kernel
OS is on an SSD, at least 20GB free space
Data drive is a 4TB HDD, tested extensively before installation
Reviewing my system logs, I do see a number of PHP Warnings. Here is the relevant messages leading up to the crash, at about 3:11pm. System was restarted at 6:17pm. I noticed the SMB Daemon reloading a few times, and all the drives unmounting directly before the crash:

A screencap of my memory usage stats is also attached. I do notice the page file size is almost all the memory. It seems that the memory was all used up, maybe due to the flash plugin? I'm not quite exactly sure though.
Sorry for the verbose post, and if I defied any conventions on this forum I am a relative newcomer to OMV. My apologies in advance.
I have attached my syslog output from the past day, if that is helpful as well.
