Email id is getting truncated even after correction

[Ct111]

Hello community members,

Has anyone come across issue where emailid gets truncated even after correction?

There are few users in our system who have very long name , as a result there userid(which consist) of email is getting truncated , 

both email id and userid have length of 151 already on sys_user table, so increasing length might not be the solution.

We do not see import records for 'sys_user' table for those records (long names).

Hence, we are confused which particular integration or script is reverting back the changes , the only thing we can see in audit history is updated by "system".

Can anybody assist here?
