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: [email protected]
Reporter: [email protected]
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.
