edit 2016-01-11: See my latest posts, I am no longer under the impression this issue is related to high load operations. The system has long since also been upgraded to 8GB RAM.
I'm having a problem where CPU and/or IO intensive loads are causing system lockups. Running up to date FreeNAS 9.3 train as of 2015/11/04. The problem has occurred for months.
Scenario:
1) SSH into the FreeNAS machine or one of its jails.
2) Attempt a long running process such as compressing a 50+GB file, or uploading very large files (1GB+) to S3, which takes hours on my internet connection.
Problem:
Approx 80% of the time, the system becomes completely unresponsive within 1 minute to an hour or so. All shares become unaccessable. Web interface will not load. Can not SSH in. Only remedy is a hard reset via power button.
We have had 99.9% uptime otherwise over 6+ months. 0 SMART problems. 0 scrub issues. Neither the boot volume or storage pool is more than 50% full. The only potential issue I can think of is that we are operating with 4GB ECC RAM, which is less than the recommended amount (although we only have 4TB storage).
Any thoughts? It feels like a hardware problem, but I'm unsure where to start.
