[jira] Created: (SLING-943) deadlock when a single thread is adding users
deadlock when a single thread is adding users - Key: SLING-943 URL: https://issues.apache.org/jira/browse/SLING-943 Project: Sling Issue Type: Bug Affects Versions: Launchpad App 4, Servlets Get 2.0.4, JCR Jackrabbit Server 2.0.4 Environment: Sling Trunk at r768397 with 1 patch SLING-940, OSX 10.5, JDK 1.5, JMX, and Debug ports open. Reporter: Ian Boston I have a script that tests adding users. When running this as a single thread, after about 7K users, Sling stops dead with the following deadlock. I have previously done runs adding 12K users.
