No, when buffer memory was used up in the middle of a request, this error will occur. LSWS cannot switch from buffer memory to swap memory in the middle of a request. Some area can be improved in the future.

2. and I have 3gb RAM, why litespeed wont use it at first place and then start to swap to tmp?

If LSWS uses all 3gb RAM for the buffer, the server will become extremely slow. So, there is a configurable limit. once the limit is hit, it will start swap to tmp for new requests.

I think we will avoid buffer large request body in the buffer memory, instead, it will go straight to the tmp swap.

Even when swap is used, it is more likely that the swap file is cached in the memory, so the performance hit is minimum, and the OS kernel has more freedom to use system memory efficiently.
