Hi guys i just move to new server


in previous server i can running mysql backup using mysqldump with no problem

mysqldump --opt -u user -p dbname > backup.sql

but in this new server, its running not completed, stopped in the middle

the mysql size total are 2.2Gb, but its only get 650Mb



please advice what should we do, current server's specs are bigger from the previous servers





here is current server's specs

Control Panel: CPanel/WHM - Centos 5 64 Bit
RAM/Memory: 8GB DDR3
Primary Hard Drive: 1TB SATA

here is the my.cnf content, from here, and please advice do you think below configuration are good for above server's specs, the server are running vbulletin big enough

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-innodb
max_connections = 500
key_buffer = 16M
myisam_sort_buffer_size = 64M
join_buffer_size = 1M
read_buffer_size = 1M
sort_buffer_size = 2M
table_cache = 1024
thread_cache_size = 64
wait_timeout = 1800
connect_timeout = 10
max_allowed_packet = 16M
max_connect_errors = 10
query_cache_limit = 1M
query_cache_size = 32M
query_cache_type = 1

[mysqld_safe]
err-log=/var/log/mysqld.log
open_files_limit = 8192

[mysqldump]
quick
max_allowed_packet = 16M

[myisamchk]
key_buffer = 64M
sort_buffer = 64M
read_buffer = 16M
write_buffer = 16M

[mysql.server]
user=mysql

You met this problem in this new server,I this the best way is to contact the new hosting provider.

Hi there,

Please try to increase:

max_allowed_packet = 128M

[mysqldump]
quick
max_allowed_packet = 128M

And don't forget to restart mysql service

You can also try to raise this limit, and try again:

wait_timeout = 1800
