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_net_write_timeout

I hope this will help you.

Kind regards, Michael
