Bug #2819: Random micro system freezes after a week of uptime
http://bugs.dragonflybsd.org/issues/2819#change-12645
* Author: ftigeot
* Status: New
* Priority: Normal
* Assignee:
* Category:
* Target version:
----------------------------------------
On a file server, the system freeze for a few seconds to more than a minute after aproximately a week of uptime.
The longer the machine stays up, the worse the freezes become. The micro-freezes happen more often and become longer.
It is a complete kernel freeze: characters typed on the console stop appearing on the screen when it happens.
Characters don't stop being displayed when the operating is stopped and the kernel debugger is active, which indicates the problem is not of a hardware origin.
Hardware specs:
- Xeon E5-2620, 64 GB RAM
- Areca RAID controller
- 2x 500GB system disks (RAID 1)
- 11x 2 GB data disks (RAID 5)
- 1x 512 GB SSD (JBOD), used entirely for swap
- 10Gb Intel X540 ethernet adapter
Software configuration:
- swapcache enabled, up to 85% of the available swap size
- deduplication enabled on the data volume
The data volume is used for two things:
- protein sequences
- a rsnapshot backup directory for various servers
