Looks good, I changed the driver.c line, replaced nsd and libnsd.so and changed writerbufsize in config to 8192: [-conn:server1:6] Notice: starting download [-conn:server1:6] Notice: Writer: 4: started sock=5, fd=7: size=24445108, flags=10: /download/ [-conn:server1:6] Notice: finished download in 0 seconds [-writer4-] Notice: Writer: closed sock=5, fd=7, error=0/0, sent=24445108, flags=10 I can stop the download and resume/restart it without errors. One note: I tested older code that does not make use of ns_writer commands, it still runs ns_returnfile. I set outputheaders to prepare for a PDF download, computed and logged duration and success or failure (both obsolete with writerthreads). When I naively replace the ns_returnfile line with a ns_writer submitfile $download_path I immediately receive an empty page (no log statements indicating some error, btw). Not that I feel the urge to replace ns_returnfile if it works... Bernd.
