After updating the Ubuntu servers I maintain on the 30 of September I'm having this problem too. However only on one of the servers which is currently running Ubuntu 14.04.5 LTS (3.13.0-96-generic #143-Ubuntu SMP Mon Aug 29 20:15:20 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux).
If I run apt-check manually with the following command: # /usr/lib/update-notifier/apt-check --human-readable 0 packages can be updated. 0 updates are security updates. It outputs quite quickly but running apt-get update tends to cause multiple processes of 'apt-check --human-readable' and causes high load. top shows the following: ## top - 11:00:03 up 11 days, 10:28, 1 user, load average: 28.85, 16.79, 7.03 Tasks: 279 total, 9 running, 266 sleeping, 0 stopped, 4 zombie %Cpu(s): 20.5 us, 7.7 sy, 0.1 ni, 70.5 id, 1.1 wa, 0.0 hi, 0.1 si, 0.0 st KiB Mem: 1013868 total, 943524 used, 70344 free, 664 buffers KiB Swap: 1046524 total, 58400 used, 988124 free. 505288 cached Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 15494 root 39 19 121672 34420 21224 D 4.5 3.4 0:03.18 apt-check 15650 root 39 19 121672 34260 21060 R 4.5 3.4 0:03.21 apt-check 16038 root 39 19 121676 34744 21532 D 4.5 3.4 0:03.22 apt-check 16144 root 39 19 121676 35260 22052 D 4.5 3.5 0:03.17 apt-check 16642 root 39 19 103884 28516 19756 D 4.5 2.8 0:02.48 apt-check htop shows mostly the same but with instead of apt-check gives more info about the command: '/usr/bin/python /usr/lib/update-notifier/apt-check --human-readable' The server also shows more average load across the board in vSphere. CPU% has increase from normally 6% to average of 33%. However I'm not sure if this is related. Also found a tread on serverfault with the same issue: http://serverfault.com/questions/471089/prevent-apt-check-from-eating- all-my-memory -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746508 Title: apt-check uses too much resources (starts too many processes) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/746508/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
