If this message is beign showed in stdlog file, you can increase the level of verbosity of that log using command pdm_logstat -vL where L is level. Default value es 50. You can increase let´s say to 500 , reproduce de error and reset again that level to 50 very quicly, otherwise you will have several log files full in a couple of minutes.
So, open up a command window, prepare the command pdm_logstat -v500, as soon as you hit enter, go ahead and reproduce the error. At the very moment you get the error message, go to the same window and repeat the command, erasing last 0: pdm_logstat -v50. Hope this helps.
