Timo,
Let me also add
max_allowed_packet = 512M.

Timo,
Thanks for this reference - I actually have been playing / tweaking
with 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

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.
