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.
