Today, in WSAD, a small file that is less than two megons is imported. The system memory consumption actually rushes from 1G to 1.6 G. The legendary Disk thrashing began to be happy, and it was originally only 30 seconds of simple import verification. After the introduction is over, the system consumption is still 1.6G or more. I don't know why, the memory occupied by WSAD is always steadily increased, so I have to restart a WSAD or even machines in less than a week.
Which is not SWT? Forget it, restart the machine.
