I guess the beginning of the written buffer is not page aligned, and the system locks pages. Thus depending on the buffer alignment, the written maximum can vary up to the size of one page.

Memory pressure? Git may consume large amount of virtual memory during some operations, but I am not sure how it is translated in the number of physical memory consumed by the process as well as what quotas could be on that system. It would be interesting to see what GetProcessMemoryInfo() returns when write() fails.
