mongooseIM-无法使用mod_vcard_odbc

Question

我已经成功设置了mongooseIM。它不会与odbc一起使用它。模块mod_vcard_odbc无法正常工作。当我输入vcard后发生错误 -

 2014-01-02 19:35:22.192 [error] <0.369.0>@ejabberd_odbc:outer_transaction:400 SQL    transaction restarts exceeded

** When State == {state,<0.371.0>,mysql,30000,<<"localhost">>,1000,{0,{[],[]}}}

我不知道为什么会出现这种错误。
