Hi all i hope someone could give me a clue where to investigate... i'm running the chat_server example from boost http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/example/cpp03/chat/... on visual studio 2010, windows 10 and i downloaded boost binaries from : http://sourceforge.net/projects/boost/files/boost-binaries/1.55.0/boost_1_55... i used a script to simulate 30 tcp clients, each thread behavior basically: 1. connect to tcp server 2. start a loop 3. send a message to tcp server 4. receive a message from tcp server 5. sleep 6. back to step 2 the strange fact is when i use windows task manager to monitor the memory consumption. The numbers from columns *private working set* and *shared working set* remains "stable" for almost 18 minutes and after that the values of *private working set* starts to increase almost 5 MB by minute. So my doubts are: 1. Does anyone ever seen anything similar before? 2. What could cause this?
