We have a monitor to dump /proc/meminfo every second during the run.
On my desktop, the result is -
At start:
time: 1471413103.386122645
MemTotal: 14193468 kB
MemFree: 13849136 kB
MemAvailable: 13789204 kB
In the middle of the run:
time: 1471413254.363430637
MemTotal: 14193468 kB
MemFree: 13811732 kB
MemAvailable: 13756376 kB
When the test is about to finish:
time: 1471413391.294215121
MemTotal: 14193468 kB
MemFree: 13286080 kB
MemAvailable: 13749416 kB
It doesn't seem memory is an issue.
The whole dump is about the same.
The MemFree and MemAvailable doesn't change much.
Thanks,
Aaron
