[vpsFree.cz: community-list] MySQL [ERROR] Error in accept: Bad file descriptor

Zdar, mame zajimavy problem. Presli jsme na nove Ubuntu (14.4 -> 16.4, fresh install) a s tim na nove MySQL 5.6 -> 5.7 A po importu DB nam mysqld vyskoci na 100% CPU a log plni hlaskami: [ERROR] Error in accept: Bad file descriptor rychlosti nekolik stovek MB za hodinu. Google zatim negativni.. Zvysit ulimit na pocet otevrenych souboru (http://stackoverflow.com/questions/37796693/mysql-0-error-error-in-accept-ba...) nepomohl. Nepotkalo to nekoho z vas? Diky -Igor
