The modules left behind are all "in use", so they cannot be removed. The stapio processes stay in the running state. Even if this testcase (and related user-space probing) fail, stap should exit cleanly and not leave behind these stuck stapio process and modules. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
