1.7 hours is plenty and a lot. Make sure your MTA's smtp service
timeout (smtp_data_done_timeout, on a smtp service feeding amavisd)
is above your child timeout setting. More common setting is few minutes,
the default is 8 minutes:
$child_timeout = 8*60; # abort child if it does not complete a task in n sec

...timeout reduced to 10s for a connect attempt - this is normal.

but the timeout was not restored in case of a failure.
A bug indeed, thanks for the report!

... and clamscan was a victim, having only 10 seconds available
for the job before it was aborted.
Here is a patch for this bug (against 2.6.2):
