note 52307 rejected from function.readfile by nlopess

Note Submitter: erik at eldata dot se ---- 5.0.4 gotcha - for some reason when upgrading from 5.0.3 to 5.0.4 the readfile call stopped reading after 2000000 bytes. Using readfile_chunked solves this. Why I don't know...? Looking at the code for readfile that calls php_stream_passthru for the real work it checks to perform an mmap call to map the entire file into memory. If mmap isn't supported it falls back to a loop using a 8192 byte buffer. Has something been changed relating to mmap? My resource limits are set high and should not be the cause: max_execution_time = 60 max_input_time = 60 memory_limit = 256M Is there a difference or new limit imposed, related to mmap...?!?
