https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217751 Bug ID: 217751 Summary: Xenstore: there is a deadlock when suspending user-space processes Product: Base System Version: 10.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: ouyangzhaowei@huawei.com If there is a user process which maybe often reads and writes xenstore, the application has been suspended after stop_all_proc is called. It held xs.request_mutex lock but in the following functions xs_write and xs_suspend will not get the lock. So the VM will hang. --=20 You are receiving this mail because: You are the assignee for the bug.=
