Look at the timestamp, there was no 10 sec timeout, it was immediate.
I know - that caught my attention right away.

The date and size indicates that it has been used very recently.
The date and size changed I think because I
restarted spamd at that time this morning after
checking the cf. 4 1/2 hours later it's still the same.

When did you install the new version?
About 2 weeks ago.
For what period of time there are no hits? Do you know how many times the
plugin was called?
I haven't had any hits since installing. Since
Sunday when the log was rotated, there are 1241
instances in the FuzzyOcr log, 404 scans and 837
cancels due to score being above/below thresholds.

There is a global timeout, usually disabled but
looks like you uncommented the 1
sec sample value.
# Timeout for the plugin, in seconds. (Maximum runtime of the plugin)
# Default value: 10
focr_timeout 20
# Use a global timeout value instead of per helper application.
# Default value: 0
#focr_global_timeout 1
Still scratching my head on the timeouts and hash db errors...
