[Building Sakai] Too many open files error

[Berg, Alan]

Hi Omer,

I am curious, is the Tomcat running SSL. If so can you send to the list the server.xml information e.g:

    <Connector port="443" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" disableUploadTimeout="true"
               acceptCount="100" scheme="https" secure="true"
               SSLEngine="on" 
               SSLCertificateFile="${catalina.base}/conf/localhost.crt"
               SSLCertificateKeyFile="${catalina.base}/conf/localhost.key" />

Subject: [Building Sakai] Too many open files error

We are seeing "Too many open files" error in our test 2.7.x (r79223)
install.. It starts from one tool and eventually kills the Tomcat..

We tried to increase the file descriptor limit on Linux but it did not
work. Any idea or suggestion?

Thanks
Omer
