I'm able to reproduce behavior that looks like the behavior described with high CPU on a single java thread. I can't be sure that I am seeing the same problem but I am seeing a problem which I should be able to fix. I'll update this ticket as I make progress.

The problem was that a return value of zero was treated as a non-blocking read that returned no data rather than as EOF. That meant that the socket was put straight back into the Poller only for the Poller to trigger a read event immediately for EOF and so the loop continued. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

Mark,
I do not think I will be able to debug the run() {..} Trying to check whether
the odd/bad state when I really have no idea what it is supposed to do.
if (((desc[n*2] Poll.APR_POLLHUP) == Poll.APR_POLLHUP)|| ((desc[n*2]
Poll.APR_POLLERR) == Poll.APR_POLLERR) || ((desc[n*2] Poll.APR_POLLNVAL) ==
Poll.APR_POLLNVAL)) {
if (!processSocket(desc[n*2+1], SocketStatus.ERROR)) {
// Close socket and clear pool
closeSocket(desc[n*2+1]);
}
}
Would the randomness of this be concurrency issues? I am running on slower
hardware (although it is happening on my new i5 box) had this before, adding
and removing at the same time, causing deadlocks.
I don't mind making changes to the source ie backtracing the mods to see which
is causing the run() to loop continuously.
Cheers Greg

https://bz.apache.org/bugzilla/show_bug.cgi?id=58151 --- Comment #20 from Mark Thomas ma...@apache.org --- Don't worry too much about why the loop is happening. Once we know the route execution is taking we'll probably be able to figure out the why. As a starting point, would it be possible for you to find out the following when the loop happens: 1. Put a break point on AprEndpoint.Poller.add(long, int, int) and tell us the full stack trace for the code that adds the socket to the Poller 2. Put as break point on ApeEndpoint.processSocket(long, status) and (for the looping socket) tell us what the value of the status parameter is. The above two bits of information should allow us to get a little further. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

if you check the private void add{..}
what did the ok do?
boolean ok = false;
synchronized (this) {
// Add socket to the list. Newly added sockets will wait
// at most for pollTime before being polled. Don't add the
// socket once the poller has stopped but destroy it straight
// away
if (pollerRunning addList.add(socket, timeout, flags)) {
ok = true;
this.notify();
}
}
if (!ok) {
// Can't do anything: close the socket right away
boolean comet = connections.get(
Long.valueOf(socket)).isComet();
if (!comet || (comet !processSocket(
socket, SocketStatus.ERROR))) {
closeSocket(socket);

https://bz.apache.org/bugzilla/show_bug.cgi?id=58151 --- Comment #17 from Mark Thomas ma...@apache.org --- The stack trace only shows where execution is at a single point in time. It doesn't show how execution reached that point or where execution will go afterwards. I suspect that something is putting a socket in an odd/bad state. The code then enters the following loop: - the socket is queued to be added to the poller - the socket is added to the poller - poll() finds an event for the socket - the event is processed - processing terminates early because of the odd/bad state What we need to figure out is what is this odd/bad state so we can detect it and ensure the socket is correctly processed (probably closed). It is possible that a timeout fired while you were looking at the code. I'd recommend increasing the socket timeout to 5-10 minutes while you are debugging this. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

at java.lang.Thread.run(Thread.java:745)
I managed to get the debugger attached and a breakpoint in AprEndpoint class
line 1802 (below), it seemed to be going in a loop which was consuming the
cpu.
// Poll for the specified interval
for (int i = 0; i pollers.length; i++) {
..
}
the variable pollers.length == 1
For some reason it stopped breaking and the CPU went back to normal, after I
held it on the breakpoint for some time as I was looking at the source, so not
sure?
Cheers Greg

Checking the source from 7.0.61 which works ok with 8.0.24 there are some
differences in the run method, maybe these need checking???
removeFromPoller(info.socket); added
rv = mergeDescriptors(desc, rv); added
differences
// Process socket timeouts
if (getSoTimeout() 0 maintain++ 1000 pollerRunning) {
// This works and uses only one timeout mechanism for everything, but the
// non event poller might be a bit faster by using the old maintain.
maintain = 0;
maintain();
}
// Process socket timeouts
if (getSoTimeout() 0 pollerRunning) {
// This works and uses only one timeout mechanism for everything, but the
// non event poller might be a bit faster by using the old maintain.
maintain();
}
Just an idea?

https://bz.apache.org/bugzilla/show_bug.cgi?id=58151 --- Comment #12 from gregh gregh3...@gmail.com --- I have setup eclispe to debug tomcat running on the server, (not done much remote debugging, so bear with me) when I attach the debugger the with a breakpoint it stops as expected, if I then remove and add it again and refresh the application it hangs and does not go back to the breakpoint in eclipse? I was expecting it to go back and allow me to step through the source. Are there any more detail instruction how to do this? Go to Run-Debug Configurations Click on Remote Java Applications, then click New. Type in the title. Note that port 8000 from the Tomcat instructions. Save and run.

I can trigger the bug by restarting apache while there are sessions active. Load on the server does not seem to influence the occurance of the bug. Sometimes the load goes down again after about 30 minutes till hours. I did not actually measure the time but I noticed that sometimes the load goes back to normal after a long time. Because of the context switching (400,000 cs/sec) that is causing the load I assume that the parkNanos call is in the neighborhood of where to look for fixes. ajp-apr-8200-exec-107 #3671 daemon prio=5 os_prio=0 tid=0x7f62a007f800 nid=0x3adc waiting on condition [0x7f624d4a6000] java.lang.Thread.State: TIMED_WAITING (parking) at sun.misc.Unsafe.park(Native Method) - parking to wait for 0xed8dfbe0 (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject) at java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:215) at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.awaitNanos(AbstractQueuedSynchronizer.java:2078) at java.util.concurrent.LinkedBlockingQueue.poll(LinkedBlockingQueue.java:467) at org.apache.tomcat.util.threads.TaskQueue.poll(Unknown Source) at org.apache.tomcat.util.threads.TaskQueue.poll(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:1066) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1127) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(Unknown Source) at java.lang.Thread.run(Thread.java:745) Thanks.

It sounds like a connection is going in and out of the Poller very quickly putting the Poller into (effecively) a tight loop.
