Geo: File descriptor leak with geo.log

I noticed on the Geo testbed, there are a lot of open file descriptors in Sidekiq for geo.log:

stanhu@sync:~$ sudo lsof -p 7183 | grep geo.log | more

It looks like this number is increasing:

stanhu@sync:~$ sudo lsof -p 7183 | grep geo.log | wc -l
1078
stanhu@sync:~$ sudo lsof -p 7183 | grep geo.log | wc -l
