"Too many open files" rears its ugly head again
-----------------------------------------------
Key: JRUBY-5051
URL: http://jira.codehaus.org/browse/JRUBY-5051
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.5.2
Environment: Ubuntu 10.04
Reporter: Tony Arcieri
Attachments: catalina.log
Even on 10.04, we are still seeing the "Too many open files" issue. We make
extensive use of OpenURI to proxy files between users and S3 (particularly file
uploads). Unfortunately I wasn't able to get lsof output before restarting this
server, however I can at least attach the Tomcat log. I've truncated it to
right where the "Too many open files" errors begin. Before that the app seemed
to be humming along swimmingly.
This is particularly troubling:
