Hello, Unfortunately I got the same deadlock in jackrabbit 1.6.1. These two threads are creating a node each under the same parent node. One of them is saving and the other is still adding it. Then the deadlock happened.
Seams basic, but is that not supported by jackrabbit for some reason? I did not hit this with jackrabbit 1.4. Is this a jackrabbit 1.6.0/1.6.1 bug ? Thanks, Antonio -----Original Message----- From: Martinez, Antonio (Antonio) [mailto:[email protected]] Sent: Friday, February 26, 2010 3:39 PM To: [email protected] Subject: Jackrabbit 1.6.0 deadlock Importance: High Hello, I've been struggling for some time with a deadlock in Jackrabbit 1.4 (see https://issues.apache.org/jira/browse/JCR-2426). Based on some recommendation in ticket I have moved to Jackrabbit 1.6.0 and used NIOFS (I'm using JVM version 1.6.0_06-b02 for Solaris SPARC) With Jackrabbit 1.6.0, after some time of intensive load in the system I hit a jackrabbit deadlock I see these bugs fixed in 1.6.1. I was wondering if any of these would fix the deadlock I'm seeing or if this is something new Thanks, Antonio JCR-2443 AbstractSession should not synchronize on the session instance JCR-2250 Base64 bug - last buffer not flushed JCR-2356 Session holds LockToken after removeLockToken in XA Environment JCR-2367 RepositoryCopier does not copy open-scoped Locks JCR-2421 Unable to create repository using jackrabbit-webapp because a directory called "jackrabbit" already exists JCR-769 Unable to login with two different Credentials to same workspace in one Transaction JCR-2332 Unable to delete a non session-scoped locked node in XA Environment JCR-2323 InputStream.read return value is ignored.
