Intermitent connection could corrupt slave database?

Hi, folks!

I've a async master to slave database replication, both 9.3.5 running
Oracle Linux 7 x64.
Today, a intermitent link that ended with abrupt interruption, and made
necessary to promote the slave database to master.
After promotion, two medium databases (<5Gb) became active without
issues, and two of our biggest databases (around 60Gb) became corrupt
with error "... read only 0 of 8192" (the already known error). The
original databases are protected - besides not yet available due link
issues, so I'm on the "safe side".

But I'm curious if this "intermitent link" scenario is already covered
(perhaps in later releases), or this is something we cannot foresee/deal
with?
