------------------------------------------
I attached MegaSpawn.java, a test that seems to aggrevate the hang problem. MegaSpawn.java is basically stress.Mix with all the non-essentials removed.

[jira] Updated: (HARMONY-2803) stress.Mix hangs on RHEL4 update 4

Naveen Neelakantam updated HARMONY-2803:
----------------------------------------
Priority: Minor (was: Critical)
Per Weldon's suggestion on the dev list, and considering that HARMONY-2963 has been fixed, it makes sense to downgrade this issue.

--------------------------------------------
Naveen, how many times did you run the test. I've ran it 100 times on Windows uniprocessor and Linux smp (with latest classlib/vm, the patch is already commited) and didn't catch the bug.

[jira] Updated: (HARMONY-2803) stress.Mix hangs on RHEL4 update 4
Posted by "Naveen Neelakantam (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-2803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Naveen Neelakantam updated HARMONY-2803:
----------------------------------------
Attachment: Mix.java.load.patch
I took a play out of the Washburn playbook:
The issue can be reproduces by patching Mix.java so that it only "load"s. The attached patch (Mix.java.load.patch) does the trick.
the patched stress.Mix will still only hang intermittently.

I am also observing that stress.Mix consistently hangs on 2cpu RHEL4. I will start looking into stress.Mix problems soon and also start a discussion on dev list.

[jira] Commented: (HARMONY-2803) stress.Mix hangs on RHEL4 update 4
Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-2803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12463554 ]
Gregory Shimansky commented on HARMONY-2803:
--------------------------------------------
AFAIK HARMONY-2187 is different. It doesn't finish because AWT code create a new thread for getting windows messages, so this thread loops entirely inside of native code. DRLVM can interrupt a thread only if it sometimes executes VM code (either from Java via helper e.g. GC safe point or from native through JNI). But this AWT thread doesn't execute VM code because no window messages are received. So this daemon thread cannot be interrupted by VM.

Does patch from HARMONY-2963 fix the problem? isn't it the same bug?

Naveen Neelakantam commented on HARMONY-2803:
---------------------------------------------
What version of Linux did you try? It could be RHEL4 specific.
It hangs for me after only a couple runs (I just tried latest classlib/vm, r512413). I've even seen a Segfault with the following message:
java.lang.OutOfMemoryError: Failed to create new thread
at java.lang.Thread.start(Thread.java:743)
at stress.Mix.spawn(Mix.java:268)
at stress.Mix.run(Mix.java:77)
Cannot allocate pool storage: 0x10000 bytes of virtual memory for code or data.
Error code = 12
SIGABRT in VM code.

[jira] Updated: (HARMONY-2803) stress.Mix hangs on RHEL4 update 4
Posted by "Naveen Neelakantam (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-2803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Naveen Neelakantam updated HARMONY-2803:
----------------------------------------
Attachment: Mix.java.noload.patch
If someone does remove stress.Mix from the x86 excludes list, please apply Mix.java.noload.patch.
It removes the "load" test from stress.Mix, which prevents it from hanging on RHEL4 systems.

---------------------------------------------
oddly enough, the patch from HARMONY-2963 does not fix this issue.
I tried running stress.Mix a handful of times and it continues to hang (although now it only hangs occasionally)
