Hi List,

Sometimes, my mysqld daemon begin to consumes 100% the connection to the server gets unstable and I get flooded in the mysql error log with these messages:

Nov  4 06:17:01 db1 mysqld: 2015-11-04  6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor

Nov  4 06:17:01 db1 mysqld: 2015-11-04  6:17:01 140682979031168 [ERROR] Error in accept: Bad file descriptor

it only stops when I restart the daemon, no query is shown in "show full processlist".

Maybe some kernel adjustment? Any ideia? 

Running centos 7 at the lastest version.
