Instructions
When a NetWorker or NetWorker process is discovered to be faulting a core dump or crash dump needs to be collected by enabling core dump and crash dump capture on the system where the faults are occurring.
Linux and UNIX systems
Check current ulimit settings for core dump capture:
ulimit -c
If this is set to 0 core dumps will not be captured.
When capturing core dumps for NetWorker or NetWorker modules please increase the setting using:
ulimit -c unlimited
Check your OS documentation to confirm how to keep this setting permanently.
NetWorker core dumps on these systems are generally located in the /nsr/cores directory.
Windows 2008 Onwards
CAUTION: Adding and amending Windows registry settings can cause problems with the OS if not completed correctly. Only make these changes if you are an expert Windows user.
Create or confirm registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps
is present and available in the registry.
Update or create the following values to generate crash dumps:
DumpFolder (REG_EXPAND_SZ): The path to the folder where the dump files will be located
DumpCount (DWORD): The maximum number of dump files in the folder
DumpType (DWORD): 0 - Custom dump, 1 - Mini dump, 2 - Full dump
Set DumpCount to 10 as this should not cause space issues when the crash dumps are created
Set DumpType to 2 to collect full crash dumps for NetWorker or NetWorker module binaries
Crash dumps will be located in the path specified in the DumpFolder registry key.
Linux and UNIX systems
Check current ulimit settings for core dump capture:
ulimit -c
If this is set to 0 core dumps will not be captured.
When capturing core dumps for NetWorker or NetWorker modules please increase the setting using:
