The OOME is due to when server reading the data, it would try to adjust the reading buffer size according to the "packet length" it read. But if the "packet length" is some random numbers, server would still try to allocate a part of very big memory for the reading buffer, result in OOM. This patch add a 64k limit to sending/receiving the packet. It's the maximum length one IP datagram can support, and we don't think the request can exceed this limit. Even if exceed the limit in normal condition, we would aware of it due to the exception. Solution has been verified using wget and telnet. status 4387: resolved fixed |
