Memcached 1.6 - Max memory auto-increase

[GoogleCodeExporter]

No matter what limit you set for memcached, the server will increase the max 
memory to use for items according with the traffic to the server;
To reproduce it:

1: Launch memcache with no options (limit is set to 64 MB);
2: Generate a high traffic load to memcached (transfer 5/6 GB of data from and 
to the server);
3: Check the server stats;

Expected result:
Max memory to use for items should stay set to 64 MB;
Result:
Memcached keeps increasing this limit according to the traffic to the server;

Memcached 1.6/engine-pu on Microsoft Windows.
Compiled using msysGit/mingw

can you include the output of "stats" and "stats settings" ? ideally two 
copies, one when the instance is started, and again after you've seen it use 
excessive memory

where did you get this code?

I don't recognize that version at all.

Original comment by dorma...@rydia.net on 23 Dec 2012 at 2:25

[GoogleCodeExporter]

I compiled memcached from the branch engine-pu 
(https://github.com/memcached/memcached/tree/engine-pu) using the makefile in 
the folder win32.
Compiler is msysgit.

closing. no movement + the "1.7.11_preview" version is highly suspicious.
