scp truncate text file busy

I am having problems with scp during a backup operation

I added a ps -ef before and after the scp operation used during the backup.

The backup is a script to backup a Zimbra Server

I am including the code segment that I am having problems

Code:

	# DRCP Section. To scp newly created archives to a remote system
	if [ "$DRCP" = "yes" ]
	then
           echo ""
	    ps -ef
           echo ""
	    CPNAME=`ls -A "$ARCHIVENAME"*`
	    SCPRC=0
	    echo "copy archive to $REMOTEHOST" remote directory $REMOTEDIR
	    if [ "$SSHKEY" = "rsa" ]
            then
		  scp -i /root/.ssh/id_rsa $CPNAME "$SSHUSER"@"$REMOTEHOST":"$REMOTEDIR"
		  SCPRC=$?
            elif [ "$SSHKEY" = "dsa" ]
            then
		  scp -i /root/.ssh/id_dsa $CPNAME "$SSHUSER"@"$REMOTEHOST":"$REMOTEDIR"
		  SCPRC=$?
            elif [ "$SSHKEY" = "rsa1" ]
            then
		  scp -i /root/.ssh/identity $CPNAME "$SSHUSER"@"$REMOTEHOST":"$REMOTEDIR"
		  SCPRC=$?
            fi
	    echo ""
	    ps -ef
           echo ""
           if [ "$SCPRC" -ne "0" ]
	      then
		    echo "Error copying archive and checksum to $REMOTEHOST"
		    mail_log
		    exit 1
              elif [ $TYPE = "full" ]
              then
		     echo "$ARCHIVENAME"
		     echo "ssh $SSHUSER@$REMOTEHOST" "rm -f $REMOTEDIR/$LAST_FULL_WEEK_$BACKUPNAME*"
		     ssh "$SSHUSER"@"$REMOTEHOST" rm -f "$REMOTEDIR"/"$LAST_FULL_WEEK"_"$BACKUPNAME"*
             fi    
	fi

I am including the log that is sent during the backup by email as attachment since is too long

How can I see which process is locking the file that is being truncated?

Try lsof it shows open files.

Thank you for your promptly response.

I will replace the ps -ef line with lsof in the code.

This script backup runs only on Saturdays, and do not have a test system that could replicate the problem sooner.
I will make the change on the code today, but I have to wait until Monday to see the outcome.

So I will have to post again in this thread next week. Sorry for the delay.

After changing the ps -ef line to lsof I did not see why the scp reports Text File busy.

I am including the new email outcome as attachment

The attachments do not accept file larger that 256KB, but the email is 1MB large so I zipped the file.

Zip is not a permitted extension so I appended a .txt to the file name

I think the problem is some kind of timeout of the scp command.

It copies successfully various files, among them two of 4GB size, before failing with this file which is a 2~3GB file
