When using tomcat 7.0.42 I used libtcnative 1.1.24-1 which comes from
debian repos
Upgrade to tomcat 7.0.50 required upgrade of libtcnative also and there
was no updated version in debian repos so I had to compile it from source
tarball downloaded here http://tomcat.apache.org/download-native.cgi
Downgrading tomcat also means downgrading libtcnative for me
Connector configuration:
<Connector port="8443" maxHttpHeaderSize="8192"
maxThreads="15000"
enableLookups="false" disableUploadTimeout="true"
acceptCount="1000" scheme="https" secure="true"
SSLEnabled="true"
compression="off"
SSLCertificateFile="/opt/tomcat/my.crt"
SSLCertificateKeyFile="/opt/tomcat/my.key" />
limits.conf is appropriate for this number of threads, however on
production server we never had more than 2000 active established connections
First lines of log when starting tomcat:
