    • Linux

      ProcessInfo::getExtraInfo will return an integer for page_faults. In some cases, the number of page_faults returned is greater than an integer, causing serverStatus to report negative page fault values:

      MongoDB shell version: 2.2.2
connecting to: test
rs:PRIMARY> db.serverStatus().extra_info
{
    "note" : "fields vary by platform",
    "heap_usage_bytes" : 337326056,
    "page_faults" : -2142822936
