Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during
any development cycle it is impossible for us to review them all.
Therefore, we occasionally resort to using automated bots to request
further testing. This is such a request.
We have noted that there is a newer version of the development kernel
than the one you last tested when this issue was found. Please test
again with the newer kernel and indicate in the bug if this issue still
exists or not.
You can update to the latest development kernel by simply running the
following commands in a terminal window:
sudo apt-get update
sudo apt-get dist-upgrade
If the bug still exists, change the bug status from Incomplete to
Confirmed. If the bug no longer exists, change the bug status from
Incomplete to Fix Released.
If you want this bot to quit automatically requesting kernel tests, add
a tag named: bot-stop-nagging.
Thank you for your help, we really do appreciate it.
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Tags added: kernel-request-3.19.0-15.15

Title:
kswapd pulls server down every 2 weeks.
Status in linux package in Ubuntu:
Incomplete
Bug description:
in 15.04 even when having plenty of RAM and swap kswpd uses lots of
CPU and might bring the machine down to a crawl making is unable to
access it over the network.
I say "might", because it's only a very clear feeling that I have. I
do not know it for sure.
Anyway the fact is that I have two server that once every 2 week ends
up totally unaccessible from the network. They can be pinged though.
Logging in locally takes a long time. Rebooting them locally takes a
long time. They have absolutely no noticeable disk IO when in this
stalled state.
