Hi Ahmad
when i want to restore koha sql file using this command mysql -uroot -ppasswd databaseName <koha.sql give me this error ERROR 2013 (HY000) at line 267: Lost connection to MySQL server during query i doing this command to much time before but it appear since two weeks if any solve can tell me.
Maybe you've got some SQL insert statements that are bigger than the allowed maximum size (maybe you are loading picture data?). You will find the parameter "max_allowed_packet" in section "mysqld" of file "/etc/mysql/my.cnf" - whatever size it is, increase it. For example max_allowed_packet = 32M In case your problem is depending on the network, increasing the timeout may help. The parameter here is "net_write_timeout", for more information see https://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_... I hope this will help you. Kind regards, Michael
