| Watch this space, but I'm pretty sure that it is (was) bad memory. It passes memtest86+ but I had issues with these kits in other machines. I swapped out the stick I believe that had the stuck bit. Unfortunately, it is a wait and see solution, as they do pass memtest86+, just not the Python test suite ;) |

| > Watch this space, but I'm pretty sure that it is (was) bad memory. It's really strange that only one very specific Python test fails if it's a bad memory issue? |

| My thinking is that in normal running, the in-use memory is below the bad bit. It is due to that test using such a large chunk of memory that it pushes the data into the bad area. I would wager that if largemem tests were run, the would error as well. |

| If you are sure that your memory has issues, don't test it, just change it. I had memory issues once but memtest86 was quick to prove memory errors in my case. I changed the memory for free since it was still under the warranty. |

| That's the real problem, I'm not *sure* it's the memory, but it does have the symptoms. And that is why my buildbot was down earlier, I was attempting to determine the bad stick and replace it. I'm just hoping I changed the right one. That is why I brought up the testing (they both pass memtest). So far so good, no test_email issues after the change, but only 2 runs in. |

| See also bpo-20118: test_linetoolong() of test_imaplib is skipped "temporarily" on Python 2.7 since 2014 :-) |

| Jeremy Kloth changed a memory stick on his physical server. I didn't see this bug recently, so I consider that the bug is fixed. Thank you Jeremy! |
