I guess that's the proper term for what we're looking at with Logic 9: Memory leaks.
Memory leak - Wikipedia, the free encyclopedia "A memory leak or leakage in computer science is a particular type of memory consumption by a computer program where the program is unable to release memory it has acquired. A memory leak has symptoms similar to a number of other problems (see below) and generally can only be diagnosed by a programmer with access to the program source code; however, many people refer to any unwanted increase in memory usage as a memory leak, even if this is not strictly accurate.
A memory leak can diminish the performance of the computer by reducing the amount of available memory. Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down unacceptably due to thrashing."
I've heard of memory leaks before, but only in connection with freeware/shareware, not big-name apps.
Oh brother.
