An ssh connection aborts with the error "File size limit exceeded"
This occurs when you are using the fsize option in /etc/security/limits.conf
This is an OpenSSH issue that is caused by the size of the /var/log/lastlog file.
Lastlog is a sparse file which is seen as being over the fsize limit set in /etc/security/limits.conf.
The size of lastlog is determined by the highest UID number in use, therefore you are likely to encounter the issue if you are using high UID numbers in your environment.
The following Redhat article describes the lastlog size issue when using high UID numbers:

Remove or increase the fsize entry in /etc/security/limits.conf until the issue has been resolved by your ssh vendor.
