The Thread Dump Trace File
The thread dump trace file is named JVM.log. It is stored on the Cisco Unified CCX server in the Log
directory under the directory in which you installed the Cisco Unified CCX Engine. This file contains
stack trace information about all threads that are running on the Cisco Unified CCX system. You can
write information to this file when you need it. In addition, the system writes information to this file
automatically if the system detects a severe system problem. When new information is generated, it is
appended to the existing thread dump file.
