AEM 6.3 users are truncated/ removed in a group

Hi All,

Actually we have a group(Authors) that having 600+ users/Members .Sometimes its truncating Users unfortunately after adding users also its happening .

Can any one suggest me to overcome this issue.

am Suggested below solution its works for temp solution or is there any permanent solution?

Everything is Interlinked.So Groups and permissions are interlinked .

In a Group(Authors) we can add another group(GroupB) /A Group can be a Member of another Group.  so.Creating a  new group and adding as a member of "@Authors" Group.

Please Help me to overcome this issue .if my understanding about Groups and permissions is mistaken please correct me .

Thanks In Advance
