Given sufficient stress, all that is required is for a client to open/close many contexts, and the aperture will be filled with inactive contexts until we are forced to evict all the inactive contexts to make space for a new one. Whether or not it impacts synmark, we can and should write an igt to try and demonstrate the DoS.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
