Daniel,
It was not related - I am still experiencing this very frequently.
The crash however was happening due to a modification I made it the Db_mysql module to further track down why it is happening.

Hello,
was it related to the item in the bug tracker (which I just closed due to PM on tracker from you)? What was the cause for it?
Thanks, Daniel

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.
