Issue #2542 has been updated by daniel.ramos. Description updated
I was able to reproduce this (or a very similar) bug on a dual-core KVM VPS running DFly 3.4.3. Basically, it was impossible to complete a "make buildworld" due to long and frequent freezes (clock skew, no response to keyboard input or ping). My setup does not use HAMMER, and changing vm.read_shortcut_enable did not seem to make any difference. Since updating to 3.5 master (by waiting out the freezes), the issue is resolved - I'm now able to make buildworld without any freezing whatsoever. ---------------------------------------- Bug #2542: Kernel freezes for minutes at a time http://bugs.dragonflybsd.org/issues/2542#change-11623 * Author: ftigeot * Status: New * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- Running the new poudriere-devel 2.3_4 port makes the system freeze for minutes at a time after a while. * This is not the case at first, poudriere has to run for at least one hour for this phenomenon to become visible * Display is frozen in place, periodically refreshed widgets such as clocks stop moving * Keyboard and mouse input is not processed but is handled after a few minutes when the system becomes operational again * Launching big applications such as firefox is enough to make the system freeze * "Warning: deep namecache recursion at (null)" messages are printed on the console When the system becomes operational again, top(1) shows one cpu thread using 100% cpu (system time). A core dump taken when the system is in this state will be made available. -- You have received this notification because you have either subscribed to it, or are involved in it.
