Hi,

I have experienced similar problems to the one you have; the problem you have 
is that the time gap between the failure and now is so big that you cannot 
resume replication, because of the big data portion you have to replicate.

When this happens to me, increasing the value of the variable you have posted 
did not work; i did:

1º Stop replication
2º Use mysqlbinlog to see what is on the repl files.
3º Manually apply the changes (on the slave, of course) to a defined position 
(50K queries far away the failure).
4º Start replication on this position, manually especifying the position on the 
command "start slave" (see manual).

This worked fine to me.

Regards.

Here's an excerpt from the logs. It does not look like that value is 
involved in this:
