We have three Talkshow VS-100S at our location and recently they're experiencing a serious memory leak problem. After the Talkshow and Skype Tx are open for 6 ~8 hours, WDM.exe eats up the memory-98%, and the system becomes frozen. If we close the Talkshow application before the system freezes, the memory usage drops significantly. I went through the windows LTSB update patches list and pushed the windows updates that were missing from before. Not sure what else to do.
Does anyone else have this problem? Thanks.
