I think that we should watch what happens with the Percona Playback
project before we invest much additional time into this tool.

I'm trying to split a 1GB slow log file and i'm getting this error:

Cannot open session file sessions/3/session-14578.txt: Too many open files at /usr/bin/pt-log-player line 1768, <$fh> line 36777.

Running this command --> watch "lsof | grep session" while attempting the split shows the split files are never being closed after creation. Not sure if there is a reason behind that, but ideally the split file should be created then closed.

Sorry, support and development for pt-log-player has stopped, and the tool will be removed in 2.2. Percona's active log-playing project is https://launchpad.net/percona-playback. pt-log-player was built for other purposes years ago, so it was never well-suited for controlled replay of logs.

Percona now uses JIRA for bug reports so this bug report is migrated to: https://jira.percona.com/browse/PT-871
