Matteo Bertozzi commented on HBASE-15100:
-----------------------------------------

that "removed logs: [a, b, c]" is a bad log message it is fixed now. that is 
the list of "active logs"
the out of order deletion is a bug which is fixed by the patch attached. which 
should be the problem of the lots of logs staying around.

The ServerCrashProcedure is something else I was looking at, especially in case 
where we fail an assignment or something like that. unsure if that procedure 
may hang forever spinning in a retry assign, but that should be easy to catch 
by listing the procedures running from the shell.
