Hi Everyone
I have a strange issue which has occured over tha last few weeks.Every morning our super admin accounts get locked out for around 10 minutes.There is no set time on this and it sometimes happens when another superadmin logs in but it can also happen on the first login of the day.The site just hangs and you cannot access the back end or the front end.The site itself is not affected as you can view it in another browser but if you try to login in that browser the same issue occurs.Another stange factor is that ordinary members can login and work away during the lockout time.
This happens once a day and we have no other issues related to it , there is nothing out of the ordinary in the server logs and there is no scheduled backups or cron jobs seup for the time this issue happens(always in the morning.
Thanks for any help
Brian
