Have a look at this link

you may find some help there.
Also look at this links
http://dev.mysql.com/doc/refman/5.0/en/error-log.html
and
http://dev.mysql.com/doc/refman/5.0/en/slow-query-log.html
try to enable slow-query-log. It might come up with an unknown slow query .
when you have those errors if you log to the mysql server can you query
anything to the db? or the server is dead?
Also take a look at this link

Come back with reports and news.

I tried your config for my.cnf but I am still having the same issue.
It appears that if mysql is restarted whatever authdaemon is looking
at is gone. It's like there is a specific PID or something and once
that PID is gone authdaemon believes mysql has stopped.
Hi!
I had a similar problem and it was being caused by excess tuning to
mysql. Now I run my mysql with this my.cnf
The issue was not with vpopmail but with web applications. A few years
ago I had a mysqld has gone away but it was because a small
max_connection value.
max_connections = 75 what is your number of max
conn?
key_buffer = 120M
max_allowed_packet = 24M
table_cache = 3072
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size = 64M
thread_cache_size = 8
query_cache_size = 128M
query_cache_limit = 2M
join_buffer_size = 1M
thread_concurrency = 2
long_query_time = 5
log-slow-queries = /tmp/slow-queries.log
open_files_limit = 6500
max_heap_table_size = 64M
query_cache_min_res_unit = 2K
wait_timeout = 60 --- Watch this value it was giving
my headache
connect_timeout = 10 --- Watch this value it was
giving my headache
interactive_timeout = 120 --- Watch this value it was
giving my headache
max_connect_errors = 1000 --- Watch this value it was
giving my headache
expire_logs_days = 7
low_priority_updates = 1
max_join_size = 4294967295
This is a dedicated server with 2G, so the others values my not apply
to your setup.
Hope that helps.
