Hello. I have a little problem when i connec to my server. I type the login and password, then a message appears saying my login or pass are wrong( they are correct ), so i retype and it accepts(it is not creating a new account cuz already exists there), but it shows no chars. I click re-login, type my info, it accepts and this time my char appears but without any clothes or whatsoever, like a new char. If i click again re-login, enter my info, now all appears well.
I guess this happens only after a certain time the server is online. If i start the server and when it is ready, if i login everything is good...but after a while this "bug" happens.
I've checked the logs and there are some messages:

Thanks

local or remote server? some other network problems?

It is a remote server. Local does the same thing. I didn't notice any other problems in the network in the remote server.
Anyone has a clue? already tested it with another version and still the same. Can it be the delay between connections? or something like that?

No one? =(

Your mysql server dropping connections.

try to get repair tables if some of them damaged

I did a repair on the tables, everything was good. I optimize it too. Still doing the same.
