Recursive queries fail after bind has been running for a few hours

I don't look at debug logs and may be WAY off base.  But the time period 
for the log seems to be about 10 seconds start to finish in the failed 
query.  However line 56 indicates that it timed out the query after 30 

That just doesn't add up to me for some reason.  Or is there 20 seconds 
of preceeding logs missing when the query started?
