Backup failing with "Text file busy" error

• The "Text file busy" error: error usually occurs when attempting to execute a file that is currently open for writing.
• The "Text file busy" error (ETXTBSY) in Linux, and Unix-like systems, indicates that an attempt was made to modify or remove an executable file that is currently being executed by the kernel.

• The " Text file busy" is reported by the operating system.
• A process has a lock on the file, and the client agent cannot back it up.
• This is like the Windows client message.
• Code 32: The process cannot access the file because it is being used by another process.

Troubleshooting :

->fuser <open directory with .lock file> (Ex : - fuser /var/tmp/netcd.lock) – This Command is used to identify which process is holding the file open.
Then it will return the Process ID which is running & holding up the file. ( Ex : - /var/tmp/netcd.lock: 32440328)

-> kill -9 PID (Ex : - kill -9 32440328)
>> Then try to Trigger the Backup & it will be Successful.

Also Note that, .lock files are temporary files. They are not normally backed up.

If this file must be backed up, then find which process has a lock on this file and resolve it from there.
