CLONE -Deadlock when logging trace
----------------------------------
Key: JBAS-4514
URL: http://jira.jboss.com/jira/browse/JBAS-4514
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: chris effenberger
Assigned To: Scott M Stark
SourceForge Submitter: genman .
This was caused when trace was enabled. I imagine it
was caused by the classloader trying to load a class
while it was being rendered (?) to disk. Probably not
a big issue, unless trace-logging is enabled.

-----------------------------------------
Ceki hasn´t implemented the fix (http://issues.apache.org/bugzilla/attachment.cgi?id=9635)
in 1.2.8.
you find the bug under: http://issues.apache.org/bugzilla/show_bug.cgi?id=24159
You can see this in the source of Category.java (or in the decompile code).
First in 1.3.alpha-8 he has a fixed version of Category.java with the helpers class
"ReaderWriterLock.java".
with the log4j1.2.8 in jboss-3.2.5 we have the following deadlock:

-----------------------
we have jboss-3.2.5 and the jdk1.4
so we have backported the new fix with the "ReaderWriterLock.java" helper class
to our own version of log4j1.2.8. I hope this works better now.

https://issues.jboss.org/browse/JBAS-4514?page=com.atlassian.jira.plugin....
]
Vadim Kopichenko commented on JBAS-4514:
----------------------------------------
A note for history and legacy users.
The deadlock is caused by known log4j 1.2.x multithread vulnerability.
See "Deadlock in Log4j when logging inside exception stack trace"
http://issues.apache.org/bugzilla/show_bug.cgi?id=43568 and
http://issues.apache.org/bugzilla/show_bug.cgi?id=24159.
JBoss 4.x has several places in code that do such nested logging while already logging
exception stack trace that causes deadlock.
At least in classloading and org.jboss.util.NestedThrowable.
The workaround is to disable that logging in jboss-log4j.xml:
<category name="org.jboss.mx.loading" additivity="false">
<priority value="OFF"/>
</category>
<category name="org.jboss.util.NestedThrowable"
additivity="false">
<priority value="OFF"/>
</category>

Assignee: David Lloyd
Fix For: 6.0.0.M3
SourceForge Submitter: genman .
This was caused when trace was enabled. I imagine it
was caused by the classloader trying to load a class
while it was being rendered (?) to disk. Probably not
a big issue, unless trace-logging is enabled.
