As part of my workaround/fix I downgraded udev and upgraded RAM from 3GB to 8GB on my homeserver.
Now I am experiencing the following which can't be normal either: top - 13:50:48 up 1 day, 19:29, 1 user, load average: 0,11, 0,15, 0,14 tasks: 200 total, 1 running, 198 sleeping, 0 stopped, 1 zombie %Cpu(s): 6,1 be, 2,5 sy, 0,2 ni, 81,6 un, 9,1 wa, 0,0 hi, 0,4 si, 0,0 st KiB Mem: 8067248 total, 4768336 used, 3298912 free, 477524 buffers KiB Swap: 4194300 total, 4170948 used, 23352 free. 2803672 cached Mem Filename Type Size Used Priority /var/cache/swap/swap0 file 4194300 4170948 -1 Linux ##### 4.2.0-25-generic #30-Ubuntu SMP Mon Jan 18 12:31:50 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Any idea?
