Error description
Netezza hardware failures behind the scenes may trigger a so-called nzPAUSE request. (The nzPAUSE request only becomes evident in IDAA/Netezza traces and logs). This request may impact updates (inserts/deletes) of tables in progress related to a replication thread When Netezza resumes operation the affected replication does not continue where it had been interrupted. A subsequent attempt to reload the affected tables would fail. A fix for the issue will be provided by delivering a new version of the Replication Engine component that has to be installed on top of maintenance level V5 PTF8.

Problem conclusion
To avoid hanging of replication threads due to hardware issue related interceptions we recommend to upgrade your accelerator maintenance level to V5PTF8 with the new Replication Engine delivered with this PTF installed on top.
