It happened here again.

8/24 ext4 corruption
9/14 ext4 corruption
9/29 update/reboot
10/16 ext4 corruption

This time the corruption was severe. 1743 files from multiple directories got moved into lost+found.
It took me almost 2 hours this morning to verify & fix everything. Fortunately every time this has happened, all the files were dated prior to the daily backup and "diff -qr ..." shows exactly what was lost.

As far as I can tell this is not a memory issue and the ext4 FS is using 10G out of 100G.

Every time the corruption has been in /var/mail. However the VM is mostly used for mail so it may not be significant. The /var/mail branch itself is 4.3G

3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u4 (2015-09-19) x86_64 GNU/Linux

I'm holding back the kernels on other VM's so this is the only VM with the problem.

Is anyone able to reproduce this on demand?

I really need to do something because this is causing downtime during normal business hours. I'll probably try one of the following:
1. Rebuild the FS from scratch and see if ext4 corruption continues.
2. Use ext3 or something else.
