We are running an Amazon EC2 R3 instance so has 30G of memory available. We are running 5 Apache Tomcats (version 7). According to lsb_release -a the version of Ubuntu is: Ubuntu 14.04.2 LTS
Tomcats keep terminating on this machine from unknown conditions. This machine is more than adequate to run many Tomcats and after a single Tomcat termination, running free -h shows at least 10G available.
When I run the command cat/proc/swaps the following is displayed:
cat /proc/swaps Filename Type Size Used Priority
Does this mean that no swap partition is in place? Running the swapon command shows the same output:
swapon -s Filename Type Size Used Priority
Running the top command shows:
Swap: 0 total, 0 used, 0 free.
So do these results show that no swap is available for when processes need it or does it show no swap is currently being used?
