You need more virtual memory (swap space). If you haven't allocated enough device swap, you can use SAM to allocate file system swap until you can add device swap.

see this other thread

also the last of the error msg indicate, there are quiet of process and hence it can't fork anymore..
but i guess once you fix the first issue, the second should be gone.

What methods to find out the real causes about the swap usage reached 99%.

You could say the system is under configured or under provisioned.
Or someone went crazy with bad programming and in a recursive fork loop.

Take a look at "ps -ef".
