Hi, I am running jetty server "9.4.19.v20190610". I have no .wars loaded and have made a bunch of http 1.0 requests to the jetty web server to a URL which does not exist resulting in a 404 from the jetty web server.
What I noticed is that after some time the web server stopped responding, I was unable to run jmap to get a heap dump I instead got the message too many open files. Running lsof on the process gave me lines like: Service 5309 5347 root 515r FIFO 0,9 0t0 172660316 pipe Service 5309 5347 root 516w FIFO 0,9 0t0 172660316 pipe Service 5309 5347 root 517r FIFO 0,9 0t0 172660317 pipe Service 5309 5347 root 518w FIFO 0,9 0t0 172660317 pipe Service 5309 5347 root 519r FIFO 0,9 0t0 172661057 pipe Service 5309 5347 root 520w FIFO 0,9 0t0 172661057 pipe cat openfiles.lsof.txt | grep 5309 | grep FIFO | wc 211947 2115471 18863283 is that expected? I restarted jetty and saw the number of those open files go up and down, like they got created and later gc'd. many thanks, Luke p.s. I found this while trying to investigate a memory leak in conscrypt and jetty.
