Last night, I noted 201506212038 was available in the 9.3 STABLE channel & I applied it to a couple of my FreeNAS systems but left a couple untouched. After reboot, I detected no problems. Today, when I connected to update the rest, the latest STABLE was 201506162331. Looking at this forum & the bug track, I could see no information about what happened. For safety, I rolled the updated systems back to the prior stable but would appreciate your consideration to post info about what the issue is to help users decide what our cicumstances necessitate.
