my.cnfoption,open_files_limit. The effect is the same as for the server: it changes the maximum number of file descriptors available to the xtrabackup process. The actual limit depends on the platform andulimitsettings. Bug fixed#1183793.CREATEd orALTERed during the backup, an attempt to prepare such a backup later would lead toPercona XtraBackupcrash. Bug fixed#1291299.innobackupexandxtrabackup, that was supposed to make sure no child processes are left running in caseinnobackupexgot killed or failed with an error, relied on the fact theSIGTERMandSIGINTsignals were not blocked by thextrabackupprocess. However, bothSIGTERMandSIGINTmight be blocked by the process that had invokedinnobackupex, for example, by thePercona XtraDB Clusterserver processes doing an SST, in which case they were also blocked by the xtrabackup process, since the signal mask is inherited by child processes. Fixed by replacingSIGTERMin innobackupex andSIGINTin xtrabackup auto-termination withSIGKILL. Bug fixed#1294782.InnoDB: in InnoDB data dictionary has unknown flags 50.” warnings.
