New issue 297 by poffenwa...@imvu.com: intermittant failure on incr of
numbers larger than 2^63-1, ubuntu 10.04
http://code.google.com/p/memcached/issues/detail?id=297
What steps will reproduce the problem?
The problem is usually intermittent but occasionally we can repeat it on an
given host as follows.
set asdf 0 200000 19
9223372036854775807
STORED
incr asdf 1
9223372036854775808
incr asdf 1
CLIENT_ERROR cannot increment or decrement non-numeric value
version
VERSION 1.4.13
What is the expected output? What do you see instead?
I am expecting it to be able to increment numbers larger than 2^63-1
consistently.
What version of the product are you using? On what operating system?
VERSION 1.4.13
We are running a unit test that does the following
set foo 0 0 20
18446744073709551615
STORED
incr foo 2
The test expects a result of 1. This test is run on dozens of virtual
machines many times a day. It has about a 1% failure rate. If you repeat
the command "incr foo 2" again it will fail again. If you repeat the "set
foo 0 0 20, 18446744073709551615" before the whole test again it will
usually pass. Occasionally a memcached sever will into a state where
setting any large integer and trying to increment or decrement it will fail
as shown in the reproduction steps above.
We are running VMware virtual machines with ubuntu 10.04 for all of the
above.
