[priyadarshan]

I have a new installation of confluence on freebsd 10.1 with jdk-8u60-linux-i586.tar.gz java installed. I have not a problem to run JIRA software, but confluence has a java problem. Tomcat is started, but I can not to connect my web browser to confluence. Log file is below. How can I fix it? Thank you for help.

Ha. The error means that epoll_create is not implemented in the OS. That's very strange. Either you have a very old OS (which seems not the case) or the freebsd team got it completely wrong

You actually made me to look into some workarounds on the internet. Some users reported that running java with: -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch .PollSelectorProvider will avoid the call

However, when I looked on freebsd wiki: https://wiki.freebsd.org/linux-kernel#Missing_stuff there's a patch: http://lev.vlakno.cz/~rdivacky/patches/linux_epoll.patch . Try it to see if this fixes something or not.

See workarounds on that page, they recommend the same thing: -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider

Hello, thank you for answer. I added two lines (look below) to file setenv.sh in confluence install bin folder and I have now web access to confluence without errors in log files. So I hope it will work all ok. Thank you again.

Two lines at setenv.sh file

JAVA_OPTS="-Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider"

export JAVA_OPTS
