Timo,
Let me also add
max_allowed_packet = 512M.

Timo,
Thanks for this reference - I actually have been playing / tweakingwith various mentioned items in this reference earlier.
My current settings are as follows:
connect_timeout = 30 net_read_timeout = 180 net_write_timeout = 180
The issue still seems to be quite prevalent. I will say that the amount of aborted connects currently (41) is way lower than the actual amount of syslog lost connection errors.
Sincerely, Brandon Armstead

I am very very very frequently seeing in logs "Lost connection toMySQL Server" --- the MySQL server that it is connecting to is less than 1 ms away (essentially sitting in the same rack).

Any thoughts on what may be happening? It seems the overall connection
(network) between the two servers is great.
The MySQL documentation enumerates a number of reasons:
http://dev.mysql.com/doc/refman/5.1/en/error-lost-connection.html (This is the URL to MySQL version 5.1 documentation.)
You may want to check those for possible matchings.
