Abstract
A method for performing a data dump includes detecting an error in a segmented application having an address space and a buffer. In response to detecting the error, the method quiesces the address space and copies content of the address space to another location while the address space is quiesced. The method reactivates the address space after the content of the address space is completely copied. The method suspends write access to the buffer and copies content of the buffer to another location while write access to the buffer is suspended. While write access to the buffer is suspended, the method redirects writes intended for the buffer to a temporary storage area, and directs reads intended for the buffer to one of the buffer and the temporary storage area, depending on where valid data is stored. A corresponding system and computer program product are also disclosed.
