I have come across this in the past, where Too Many Files exception and
jetty shutting down. I tweaked file server limits and it seemed to go away.
But it seems like it is back.


I am running jetty jetty-9.2.13. I have bumped my file system max for the
system and for the user running the jetty process. Any thoughts, I am
running embedded jetty for websocket usage primarily. Any thoughts on best
practices or how to avoid this error?


OS:

CentOS release 5.11 (Final)

Linux jetty12.6.18-404.el5
