Description:

The following output is seen in the Spectrum Control Panel and <SPECROOT>/SS/VNM.OUT file:

ERROR at ItcRequestParmsCorba.cc(92): CORBA request timed out after 60000ms, possible performance problem.

This indicates there was a delay with information being processed in the SpectroSERVER. The output in the <SPECROOT>/SS/VNM.OUT file will look like this:

Dec 20 08:26:46 ERROR at ItcQdItem.cc(219): elapsed wait time = 60000 milliseconds.

Solution:

Additional debug was added to hotfix patch H04 for Spectrum 9.2 and above to automatically create stack dumps if a delay occurs within the SpectroSERVER process for more than 3 minutes. This debug is enabled by default via the following setting in the <SPECROOT>/SS/.vnmrc file (the entry is not there by default but is enabled by default):

enable_itc_moot_perf_debug=true

Please note that this debug does not work on Linux if the pstack utility is not installed.

It is not recommended to do so, but if you need to disable this debug because the .moot.trace file is over 1GB in size, set the value to false and then stop/restart the SpectroSERVER:

enable_itc_moot_perf_debug=false

If you are seeing that the *.dmp files are being created, please zip up the entire <SPECROOT>/SS/support directory. Open an issue and provide the zip file as well as a copy of the $SPECROOT/Install-Tools/.history file and the <SPECROOT>/SS/.moot.trace file.

CA Spectrum Support will analyze the stack dumps and the version of Spectrum you are running and provide you with an analysis and recommendation to resolve or further debug.

PLEASE NOTE: Depending on the stack information, further performance debugging may be needed.
