Hi Joshua, Thanks for the tip. We tried the same and here are some of the observations. 1. Debugging the Apache on the single threaded environment - issue not reproducible. 2. We upgraded to Apache version 54, and tested 7 parallel downloads (from different machines). All went successful. 3. Diverted the users on to Apache version 54 (300 users). The problem surfaced again. 4. Peculiar thing to notice is: if one download aborts (exit signal Aborted) all the other downloads exit at the same time. 5. on Apache 2.0.50 the download was failing consistently but on Apache 2.0.54 the download fails randomly. but if it fails - all other downloads exit at the same time!!!!. Can anyone help us in this? Regards Ganesh --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
