In the Presstore log file, a messages similar to this one appears:

"nsd(63930,0xb0a8d000) malloc: *** mmap(size=2013265920) failed (error code=12)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

unable to alloc 2013265920 bytes"

Presstore uses AOLserver. AOLserver has a 2GB Limit for the nsd process on 32-bit systems.

Here are several links discussing these errors:
