Comment #2 on issue 297 by [email protected]: intermittant failure on
incr of numbers larger than 2^63-1, ubuntu 10.04

Answers to your questions:
We have never had it occur with smaller numbers the repro case I showed can
be repeated once it gets into the state that allows repro with freshly set
values.
We have detected it in our testing builder which are likely only serving
one test at a time. There could be simultaneous requests in a test but the
memcache server could not have more than 2 or 3 requests to fulfill at a
time and far more likely only 1. When we are manually reproducing
the "glitch" with telnet it is definitely only 1.
I have not yet tried it with 1.4.15 but I can. It will take some time to
upgrade enough builder to catch the intermittent in reasonable time.
I have on occasion done a get after the error and the
value "9223372036854775808" is return as you would expect if the increment
failed.
