"No logs exist" and things get worse
I have been running a ReadyNAS Ultra 6 Plus (6x2 TByte in X-Raid 2 mode) for some years with few problems and much success. The device was always upgraded to the latest RAIDiator and has been running...
Ok, I have gone over the logs now and reconstruct a timeline of what happened.
Oct. 1, 2013: I installed CrashPlan 3.5.3. For the next few months it worked beautifully.
~ Mid-December 2013: CrashPlan performance starts rapidly deteriorating as the amount of backed-up files (~ 3 TBytes in mostly large files) starts hitting the java memory limit of half a gigabyte (of 1 gigabyte installed memory).
Dec. 23, 2013: CrashPlan hits the memory limit hard, crashing, leaving a 136 kByte jna*.tmp file in /tmp, and restarting. Backups basically stop but because the CrashPlan client manages to connect to the mothership every time before it crashes, I don't any warnings from them that the client is no longer running.
Jan. 18, 2014: The tmp files have used up almost all the space on the system partition and other unrelated services start malfunctioning. I post here and a few hours later the partition is completely full and the ReadyNAS is basically bricked.
Jan. 30, 2014: ReadyNAS is able to log themselves in remotely and fix the problem by moving the contents of /tmp to another partition. I change the Java memory limit to 2 GByte, which ends the crashes, but slows down the CrashPlan startup so much that it is basically useless.
Feb. 5, 2014: I get the GSkill 2x4Gbyte memory modules recommended in the above-linked thread, install and test them. CrashPlan works at full capacity once again.
