Hi team, I am periodically seeing the following crash when the new quill tries to compute checksum of an output file used by a job. I used the mmap function to map in the data from the file before passing it to the checksum function. The return status is checked to make sure that it is not MAP_FAILED before doing checksum.
Are you sure mmap is the right way to go? What if the file is bigger than your address space?
