Hi, My Susue linux/tomcat 6/struts 1.x always hang, when at hang, all the link/application's screen output is just 'null', no matter how to refresh/reload or click new link. 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. I search many similar post on google.com, but no one tel the exact reason. 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? tks in advance. pls help. john
