Hello, I am getting following error when calling innobackupex from shell script. innobackupex: Error: mysql child process has died: at /usr/bin/innobackupex line 1051. Although when running same command from shell prompt. It executes without any error. perl /usr/bin/innobackupex-1.5.1 --slave-info --user=XXXXX --password=XXXXX --databases=XXXXX --defaults-file=/etc/my.cnf --no-timestamp /home/fullbackup I tried xtrabackup-1.6.4.tar.gz & xtrabackup-1.6.5.tar.gz but same error in both of the versions. ---

A lot of times this happens due to the wrong working directory, or due to the MySQL wait\_timeout being exceeded. ---

I sorted out. I were using PATH variable in my shell script, as soon as i changed the name of variable. It’s working fine. I thought it is reserved word, environmental variable conflicting with the innobackupex script.
