Title:
  Kernel memory leak introduced with 14.04 kernel when used with squid3

Status in linux package in Ubuntu:
  Incomplete
Status in linux-meta-lts-trusty package in Ubuntu:
  Confirmed

Bug description:
  I have a Ubuntu 12.04.5 LTS running in a Hyper-V VM for several years.
  Since I updated the system a few days ago to Linux 3.13.0-68-generic x86_64, the machine hangs
  with out of memory after about 2 days of uptime. (occurred several times)

  With the kernel from July (3.13.0-4?-generic x86_64 or 3.13.0-5? - I don't remember) there was no problem
  running the machine several month without interruption.

  I'm currently monitoring /proc/meminfo and /proc/slabinfo and can sea a steady increase of
  Slab in meminfo.

  I also have a second VM without showing the problem. The VM with the leak is used as internet
  router and firewall. Two things apply to the VM the the other does not have:
  - vsftpd is running, some files are downloaded from the machine every few minutes to hours.
  - there is a "tcpdump -i eth0 -s 65535 -C 100 -W 1000000000 -w /somefile" running all the time.

  The attached zip file contains the hourly logs of /proc/meminfo and /proc/slabinfo;
  *_151115_171444 are the first files after the last reboot.
