If Centrify DirectAudit is uninstalled or the service is disabled, the Java process works fine.  


Prior to Suite 2015.1, the Direct Audit NSS library uses the system call select() to process its interprocess communication with the DirectAudit daemon (dad).   The select() call requires a bit mask of file descriptors to check. However, the system macro that we use to set the bit mask does not work correctly where the file descriptor is a large number (which is a possible case for applications that opens a lot of files/sockets, such as JVM), leading to unpredictable memory corruption.  We fix this in Suite 2015.1 by re-implementing the interprocess communication without using the select() call.


enable nscd


Upgrade to Enterprise Centrify Suite 2015.1 that has DirectAudit package included (CDC 5.2.3 with CDA 3.2.3).
