Fixed In Version: device-mapper-multipath-0.4.7-34.el5_5.4
Doc Type: Bug Fix
Doc Text:
Adding and removing a path in quick succession could have caused it to be removed while the multipathd was still using it, which used to lead to a segmentation fault. This has been resolved, and multipathd no longer crashes when the path is added and quickly removed again.
