New 3.0.0 and 3.0.1 server have memory leak issue

My server host by using a CVM (cloud virtual machine) only has 4GB of RAM
when the server is up and running for about a few minutes or a day it crashed and the error message I get is 0x0000000000 The memory could not be read. something like this. The debug file also showed no abnormal. just a simple uptime count
This is quite annoying. because every time when I have the most fun, the server suddenly crashes.
