Elena Stepanova added a comment - 2017-06-20 11:32 Since nobody was able to reproduce it, we have no other option but close it for now. If we ever encounter it, we'll re-open the issue.

Olivier Bertrand added a comment - 2017-05-17 16:22 - edited I am not sure but I think this was the copy of this bug description. I don't have it handy anymore. My system is Windows 10 and I am using a MariaDB made from source. I had seen this once in a while but very rarely. No wonder it is difficult to reproduce. About the cnf file, I don't know where it is? How can I find this?

Elena Stepanova added a comment - 2017-05-17 15:20 - edited bertrandop , could you please attach your cnf file(s) or paste the output of SHOW VARIABLES ? Also, which Windows is it? Are you using your own build or a release one?

Sergei Golubchik added a comment - 2017-04-25 17:22 Sorry, but I cannot repeat it. Both on Linux and on Windows I've got the same result: "Got error 122 'Field 2 too long for m line 2"

Olivier Bertrand added a comment - 2017-04-24 09:53 - edited I had the same problem with MariaDB 10.1.23 on Windows. After CONNECT returns the error 122 with a table status of 2, I could trace in debug mode all what MariaDB does until finaly returning from the function static VOID CALLBACK io_completion_callback line 575 of threadpool_win.cc . However, the calling client remained busy until after a timeout, the following message was issued by the system (unfortunately in French): Impossible de lire les données de la connexion de transport: Une tentative de connexion a échoué car le parti connecté n'a pas répondu convenablement au-delà d'une certaine durée ou une connexion établie a échoué car l'hôte de connexion n'a pas répondu. Note that the server was still alive and working after that message was issued. Note also that I had the same problem of the server not returning after CONNECT reported an error in circumstances I cannot remember now.

Alice Sherepa added a comment - 2017-04-24 08:07 - edited [note] I tried to reproduce on 10.1.22, Ubuntu 16.04. and got proper error message ==Got error 122 'Field 2 too long for m line== in both cases.
