Hi, My Susue linux/tomcat 6/struts 1.x always hang, when hang, all the link/application's screen output is just 'null', and all the clients access hang too. no any error messages in any of catalina.out, catalina.log, local.log .. the only solution is to rebounce the tomcat 6, then everything back to normal. Any expert here can give me the suggest for how to debug? at begining, i suspect the application(struts 1.x) cause the problem, but if that is the case, i should see error message in logfile. but no error message at all. Looks like the problem either from configuration of Tomcat or db connection pool setting, but how to debug? Should i set parameter of JAVA_OPTS? or use default is fine? tks in advance. pls help. john
