@0xd3adsh3ll,
provided your config is not correct,
-->>session.save_path is correct (tcp://172.18.45.69:5000)
session.ini have different setting.
mcrouter wrong config,
-->> "A":{"servers":["172.18.45.100:11211"]},
"B":{"servers":["172.18.45.101:11211"]}
You memcached server 172.18.45.138:11213

Hello,
thanks for your reply.
@Testinos my session.ini have a two strings for save_path
1 - uncomment string 172.18.45.138.11213 - it's old instance memcached - work fine because without mcrouter
2 - comment string 172.18.45.69:5000 - it's mcrouter - doesn't work
Schema like this:
Old work fine
|--php_app (session.save_path = tcp://172.18.45.138:11213)
|-------172.18.45.138:11213 - memcached server

New schema:

|--php_app (session.save_path = tcp://172.18.45.69:5000)
|
|---mcrouter
|-----------"A":{"servers":["172.18.45.100:11211"]}
|-----------"B":{"servers":["172.18.45.101:11211"]}
don't work and app crash with error:
"session_write_close(): Failed to write session data (memcache). Please verify that the current setting of session.save_path is correct (tcp://172.18.45.69:5000)"

@0xd3adsh3ll,
set key via telnet work fine?
-> telnet 172.18.45.69 5000
-> set test 0 60 4
->1234

and show mcrouter log file or output.

Oh...
Can you tell me please route AllAsyncRoute doesn't work in mcrouter? I can't find AllAsyncRoute in wiki.

[Testinos]

@0xd3adsh3ll Information from this issue #8 AllAsyncRouter router work.
If you don't want get error if one server down try usage option for set "AllFastestRoute"

[0xd3adsh3ll]

@Testinos hello
currently my mcrouter config is:
http://pastebin.com/wKu7c6Cp
and my /etc/php5/conf.d/session.ini:
http://pastebin.com/1UfTGeNs
So, application work fine, I don't have any errors, but if config of mcrouter replace on:
http://pastebin.com/zuzut4Mw
then application doesn't work with errors:
"session_write_close(): Failed to write session data (memcache). Please verify that the current setting of session.save_path is correct (tcp://mcrouter:5000)"

"sets" doesn't work correctly with AllAsyncRoute? I need replicated "set" to both servers with memcached and async the best solution for this but I don't understand why it doesn't work.

[ryanmce]

The all async route always returns "not stored" since it returns to the client before it hears back from the server. The client interprets this as an error. You should use something like the all first route or the all sync route, or change your client to interpret "not stored" as a non-error.

@ryanmce I think AllFirstRoute good idea for me, and it's works very well.
Thanks a lot.
P.S. I'm confused because I'm was testing configuration with "AllAsyncRoute" with memcached php function "add_server" and this works fine, also I'm was testing with java app and work fine too, but php5 and memcached.so don't works. :(
I close this issue.
