looks like you ran into issue with too many open files, please try to search on how you can resolve that on your OS. As far as I remember for linux you could try to change the limit using this command:
ulimit -f 5000
Once the limit is changed restart application server and you should be ready to go.
thanks for replying.
using the command ulimit -n 10240 changes the limit of open files.then the server woks fine.
but i got another problem.
when I use locahost:8080/drools-guvnor ,server works fine. After changing the bind address 188.8.131.52 in standalone.xml and using 184.108.40.206:8080/drools-guvnor to visit the sever(I use the standalone.sh -b 220.127.116.11 to start the server),it works fine.
then I create and edit a BPMN file in this page.when I save this file and reopen it, the file I designed is gone! it is a new one.
after that,I check the files in jbpm-installer. I find that there is no /repository folder.(when I use localhost:8080 to visit,there 's a repository folder).
I don't know what to do.and I also want to ask how to change the bind address .I modify the standalone.xml,the use command ant start.demo,but it doesn't work.
for more details see the sever.log
server.log.zip 14.7 K
