error when dumping large dbs

I have a CentOS box hosting about 60 accounts.
The specs:
P4 3.0/HT
1 GB of RAM
cPanel/whm

when reviewing the daily cron email from cpanel I notice there is an error when dumping large dbs:
Code: 
Grabbing mysql dbs.../usr/bin/mysqldump: Error 2013: 
Lost connection to MySQL server
during query when dumping table `tablename` at row: 226921
Here is my /etc/my.cnf
Code: 
[mysqld]
max_connections=500
safe-show-database
max_allowed_packet=16M
skip-locking
skip-innodb
query_cache_limit=1M
query_cache_size=32M
query_cache_type=1
interactive_timeout=100
wait_timeout=3600
connect_timeout=10
thread_cache_size=128
key_buffer=16M
join_buffer=1M
table_cache=1024
record_buffer=1M
sort_buffer_size=2M
read_buffer_size=2M
max_connect_errors=10
Is this error a bug in cpanel backup script or due to bad configurations?

Any help is highly appreciated
