The interworx import works by writing the file in the /tmp directory by default and the large sized accounts cannot be written into /tmp due to space issues.
So we need to manually change the directory path ( dir path) in the interworx default configuration file.
/home/interworx/iworx.ini
+++++
# vi /home/interworx/iworx.ini
[dir]
cron=”/var/spool/cron”
domainkeys=”/etc/domainkeys”
log=”/var/log”
mysql_base=”/var/lib/mysql”
service=”/service”
skel=”/etc/skel”
sysconf=”/etc”
tmp=”/usr/local/src”
+++++
The tmp option should be changed from /tmp to /usr/local/src and then restart the iworx service.
# systemctl restart iworx.service
