Truncated (corrupt) documents after replication

For the second time we have made major changes to a database which has 3 replicas. When user activity commences updated records are being truncated with just a combination of the following fields: $Ref, $Revisions, $Updatedby remaining. The document size property shows nn (bytes) + (truncated). One thing we have spotted is that the Do not maintain specialized response hierarchy is checked on one of the replicas and not on the other but that is the only thing we can see.

We have logged this issue previously with IBM support when it occurred earlier this year without success.

Creating a new replica seems to resolve the issue but is very time-consuming and leaves us with an unresolved problem.

Any ideas/suggestions are most welcome.
