Call for help about the problem "java.lang.OutOfMemoryError: unable to create new native thread" in Tomcat5.5.26
Hello everyone,
I meet one problem of OutOfMemoryError when I am running the Tomcat5.5.26, the following is the detail of stack information.
Nov 29, 2009 12:41:16 AM org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run
SEVERE: Caught exception (java.lang.OutOfMemoryError: unable to create new native thread) executing org.apache.tomcat.util.net.LeaderFollowerWorkerThread@958b36, terminating thread
Exception in thread "SIGTERM handler" java.lang.OutOfMemoryError: unable to create new native thread
at java.lang.Thread.start0(Native Method)
at java.lang.Thread.start(Thread.java:574)
at java.lang.Shutdown.runHooks(Shutdown.java:128)
at java.lang.Shutdown.sequence(Shutdown.java:173)
at java.lang.Shutdown.exit(Shutdown.java:218)
at java.lang.Terminator$1.handle(Terminator.java:35)
at sun.misc.Signal$1.run(Signal.java:195)
at java.lang.Thread.run(Thread.java:595)
I think that maybe it's because there are two many threads and I want to set the JAVA_OPTS (-Xss=2048 -Xss:Set thread stack size).But I am not sure.
Can someone give me some advice, thanks in advance.

Just to provide you with even more options then : as far as I know, you
can run PHP as an output filter in Apache httpd. So you could forward
the request to Tomcat for the JSP part and, on the Tomcat response,
apply your PHP output filter in Apache on the way back.
As a matter of general application design however, I must say that I
find this combination rather on the heavy side. I mean Java /and/ PHP.
What is it that you absolutely have to do in Java, and in PHP, that you
cannot substitute by just one of them ?

Sure. When requesting help from the list, for each problem, the first
email you send should be a new email and not an edited reply to someone
elses thread - which is referred to as 'thread hijacking'.
Please start over, be sure to include your OS and JVM version.
