Get an error from eventmachine
Today I am doing a test to see how many concurrent connections that a eventmachine can support, but got a error like this.
ruby: ed.cpp:938: void ConnectionDescriptor::_WriteOutboundData(): Assertion nbytes > 0’ failed.`
After investigation I found the solution:
- Only call EM.epoll before calling EM.run
- Only call EM.set_descriptor_table_size before calling EM.run
