Issue #2819 has been updated by ftigeot.
The /data filesystem contains about 5 million files. 95% of them are hard links or subdirectories in the rsnapshot directory. ---------------------------------------- Bug #2819: Random micro system freezes after a week of uptime http://bugs.dragonflybsd.org/issues/2819#change-12647 * 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 -- You have received this notification because you have either subscribed to it, or are involved in it.
