Yes. Just use SafeArrayDestroy;
SAFEARRAY *psa;
//safearray created
SafeArrayDestroy(psa);

What does your SAFEARRAY contain as elements (BSTR , integer etc)? What problem are you facing when you are destroying the array?

The type of my safearray is VT_UI1, I use it to hold the data which is received from windows socket.
After I created the safearray, I post it's descriptor to another thread which is responsible for firing events to the COM client.
Then I destroy the safearray after the fire_XXXX call returns. I checked the return value, everything is OK, but I found the amount of memory usage is increasing.
I'm sure it is not locked when I destroy the safearray.

What funstion are you using to create the SafeArray.
SafeArrayCreate or SafeArrayAllocDescriptor. Since you are using are a variant type you need not use SafeArrayDestroyDescriptor.
Create using SafeArrayCreate, destroy using SafeArrayDestroy
