Error description
APAR opened per request of L3 (KS) and dev (SM) Environment: Any Unix environment - This occurs for all logging within ITNM, but as 3.8 implements log file rotation for the .log files, the problem is only obvious with .trace files on 3.8 and all .log files on 3.7 Installed products + versions: All versions of ITNM Current behavior/symptoms/Problem description: When a trace file reaches 2GB, the process associated with the trace file cores. This is a problem when attempting to run higher debug levels for extended period of time to capture a failure. Expected behavior: For the .trace files on 3.8 to roll over when reaching a certain size. Steps to recreate: The easiest way to replicate the failure is to turn on debug 4 on ncp_disco, start a discovery of a large network and the ncp_disco process will likely fail before completion. For ncp_model - Simply turn on debug 4 and run the CreateAndSendTopology stitcher.

Problem conclusion
Trace files are now opened with support for large files so it is now possible for trace files of > 2GB to be created on Linux platforms. In addition to the above it is now possible to rotate trace files but in order to do so you must set one of the environment variables such as NDE_LOGFILE_MAXSIZE to define when the rotation should take place. The debug level will change to 0 just prior to the trace file rotation and then be restored to its original level once the file has been rotated. The default is to allow trace file rotation however a new configuration option named enableTraceFileRotation has been introduced into the CtrlSchema.cfg configuration file to allow this feature to be disabled.
