Hello all,
I'm running tomcat 5.5.23 on CentOS5 machine, JAVA1.6.2. Once every few days, Tomcat hangs. The Servlet deployed into it seems to be still running (keep writing to log), but telnet to 8080 hangs, browsing to tomcat' homepage hangs. Catalina.out doesn't show any exceptions, thread dump of the JVM running the tomcat does not show any stuck thread. Load on the tomcat is not heavy, about 20 requests per minute. Restarting tomcat helps, until the next stuck. Can anyone please advice how to debug and track down this problem? Thanks, Barak.
