[Bug 264867] kevent EVFILT_TIMER, timer expiration with twice the period

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264867 --- Comment #7 from firstname.lastname@example.org --- Hi Mark, unfortunately I have to share the system with other engineers, so I'll try to run the test with the cpuset command as soon as possibile (hopefully during the weekend). In the meantime I can add some info: - I didn't specify the target cpu when arming a callout, nor when using kevent - the original problem fired on a multithreaded program, but only one of the threads was calling kevent(), the others were receiving data on sockets. The program run at priority 0, but not pinned to any cpu. I somehow suspected that multithreading could fire the problem more frequently, so I wrote the multithreaded test program I attached to this bug report, but the original problem fired while a single thread was calling kevent with a 50ms period. -- You are receiving this mail because: You are the assignee for the bug.
