Yes, and my box have default 1024 opened file limit, yesterday before
sleep i've setup for 4096 and for 2h nothing happened
Maybe HTTP should be throttled or childs must be reused more times, my
doubt is why i have 20Mbps DSL but i live South europe download time
is longer, and lock file start since download start to decode
This evening i open jira with full limits and enviroment specification
of my box and put in cron a check each minute using lsof to monitor
and stats opened file by viewer
