[SAC-HELP] Spectrogram command help

[Kathryn Warren]

I am trying to create spectrograms using seismic data associated with snow avalanches.  For my most recent data the Spectrogram command keeps giving me errors 
Instability detected in spectral                                            estimator, increasing ridge regression                                          factor to 1.00000e-04.

Error:  Could not stabilize high res. spectrogram

or

segmentation fault

or 

crashing the SAC program.  Any help on this issue would be greatly appreciated.

Thanks,
