Fixed In Version: qpid-cpp-0.30-4 Doc Type: Bug Fix
Doc Text:
It was discovered that when two journals concurrently requested a new journal file from an empty EFP, the Broker could segfault. A fix to popEmptyFile now performs an _atomic_ test-and-create-and-grab for the EFP file, which prevents the segfault from occurring.
