We once faced a similar Issue at QV11.2 on the server, RAM- and CPU-Usage went up for almost half an hour but then it stopped.
I googled a little to solve this issue and found following:
CNTServiceis the class which provides a C++ framework upon which you can develop your own MFC C++ based services. The class makes heavy use of virtual functions which your service class should override.
That doesn't answer your question and you probably already found that yourself, but maybe it helps another person who might have the same issue has some use of it..
What was odd was, that the moment it stopped there was another error: "SE_LOG: When AAALR(6.675912) is greater than 1.000000, we suggest using new row applicator to improve time end mem effeciency." I have no idea if there is a connection between the two but after this AAALR-value went down again there was no further problem...Usage dropped and everything seems to work fine since... also the AAALR-value didn't go up again...
I also checked on that, but as no one seems to know what exactly this AAALR-value means (best shot was: SE_LOG: when AAALR(6.186927) is greater than 1.000000, we suggest using new row applicator to improve time and mem effeciency.) I couldn't determine, if there was a connection... If anyone has further information to each of these issues please feel free to share, I would really be interested, IF there is a connection or if it was just a coincident that these two came along together....
