Comment 3 for bug 1193474

We are also having this issue. We have 6 different tables containing syslog data from numerous network devices.
All tables are affected by this behavior, the smallest containing about 4M rows, the largest containing about 2B rows.
During most of the process, we average anywhere between 300K-450K rows archived per minute. It seems that once
the last block of rows is reached, pt-archiver just stalls during the final SELECT and basically spins its wheels
for hours and hours on end.

Complete command-line used to run the tool:
pt-archiver --commit-each --bulk-insert --bulk-delete --limit 1000 --progress 10000 --no-check-charset \
--source h=localhost,S=$liveSock,D=$database,t=$table,u=$user,p=$pass \
--dest h=localhost,S=$archiveSock,D=$database,t=$table,u=$user,p=$pass \
--where "deviceReportedTime < DATE_SUB(NOW(), INTERVAL 35 DAY)"

Tool --version:
pt-archiver 2.2.16

MySQL version of all servers involved:
Percona Server using TokuDB storage engine (tokudb_lzma compression) version 5.6.28-76.1
