Subject Tomcat dying unexpectedly (Tomcat5.0.28, apache2.0.54 and mod_jk 1.2.5 on Solaris 8)
Date Thu, 02 Jun 2005 09:58:16 GMT
I’ve tried to configure tomcat 5.0.28 with apache 2.0.54 through mod_jk connector (mod_jk.so
used from file jakarta-tomcat-connectors-jk-1.2.5-solaris8-sparc-apache-2.0.47.tar.gz at jakarta.apache.org)
on Solaris 5.8 (Solaris 8) platform but tomcat is dieing after some time with java.net.SocketException
exception. Please help me to get out from this issue

Following are the logs and configuration files.
