Title:
Kernel memory leak introduced with 14.04 kernel when used with squid3
Status in linux package in Ubuntu:
New
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.
