The java process at the top is a minecraft server; the machine has hung regardless of this running. ,In reviewing today's syslog, here is what I noticed...
Swap
KiB Swap: 2097148 total, 371812 free, 1725336 used.
If grep -i swap /etc/fstab
shows this...
/swapfile none swap sw 0 0
Note: Incorrect use of the dd
command can cause data loss. Suggest copy/paste.
sudo swapoff - a # turn off swap sudo rm - i / swapfile # remove old / swapfile sudo dd if = /dev/zero of = /swapfile bs=1M count=4096 sudo chmod 600 / swapfile # set proper file protections sudo mkswap / swapfile # init / swapfile sudo swapon / swapfile # turn on swap free - h # confirm 16 G RAM and 4 G swap reboot # reboot and verify operation
Edit sudo -H gedit /etc/default/grub
and change the following line to include this extra parameter. Then do sudo update-grub
to write the changes to disk. Reboot. Monitor hangs, and watch /var/log/syslog
or dmesg
for continued error messages.
GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash libata.force=noncq"
grep -i postfix /var/log/syslog*
to see the hard postfix errors...

However, if you're running this script locally you'll have to do a bit more work to collect the backgrounded PID and then kill it after cypress run.,Typically you will need to boot a local server prior to running Cypress. When you boot your web server, it runs as a long running process that will never exit. Because of this, you'll need it to run in the background - else your CI provider will never move onto the next command.,If you are running long runs on Docker, you need to set the ipc to host mode. This issue describes exactly what to do.,Most CI providers will automatically kill background processes so you don't have to worry about cleaning up your server process once Cypress finishes.
npm install cypress--save - dev
cypress run
npm start & cypress run // Do not do this
npm start & wait - on http: //localhost:8080
