Hi Alex, this problem just got a lot weirder: - Upload works fine with debug_options ALL,7 ALL,8 or ALL,9. - Upload fails with debug_options ALL,6 and lower. I created a debug_options ALL,6 cache.log. http://94.16.117.186/squid/cache.log.3b.gz During this test, the following happened at the client: Stall at 20:10:38 Recover at 20:12:47 Stall at 20:14:11 Failure at 20:16:17 Any ideas?
