Virtual memory eventually renders drives unusable
Serious memory leaks are being caused by the newly-released Aperture 3, complaints on Apple's support forums suggest. Affected users note that virtual memory can spiral out of control, to the point that it can consume all of the free space on a Mac's hard drive. This can result in a Mac becoming unusable, either extremely slow or ultimately hanging.
The precise origins of the leaks are uncertain, as several different actions have been linked to the issue. For some people leaks may begin by trying to import an older photo library; others claim the problem is tied to enabling the new Faces feature. The program may even start leaking immediately after launch, or not at all, which may raise the question of whether outside circumstances are involved.
Apple has yet to publicly confirm any leaks or mention a timeline for a fix. Such a policy is standard for the company however, which regularly remains quiet on troubleshooting issues until patches become available. A temporary remedy is said to involve forcing Aperture to operate in 32-bit mode, capping the amount of memory it can access.
