      Description

      **Reported in Launchpad by Peter Zaitsev last update 31-05-2012 08:15:33

      Server is configured with innodb_open_files=10000 and open_files_limit=30000

      Xtrabackup is backing up 10000+ tables and is crashing with error 24 (out of file descriptors mid way thought)

      ulimit -n 30000 before running it fixes the problem.

      xtrabackup should handle open_files_limit option and increase number of limits and refuse to run or reduce number of allowed open files if needed. Alternatively we may restrict innodb_open_files setting as xtrabackup does not need many open files for operation.
