You are probably trying to insert the same process definition. This is the failing constraint:

<code>
alter table ACT_RE_PROCDEF
add constraint ACT_UNIQ_PROCDEF
unique (KEY_,VERSION_, TENANT_ID_);
</code>

So basically, you are trying to deploy the same process (same key) multiple times at the same time.
There are very little use cases why this would be something you actually want.

Thanks jbarrez. So in an environment containing 12 clusters or rather 12 managed servers. How should i proceed with the deployment?
Should I deploy the activiti processes in one server and leave the bpmn processes from deploying in other servere??? Should this be my approach?

You typically only want 1 deployment of a specific process definition for a cluster of Activiti Engines. Are you using auto deploy? Otherwise you should only deploy a process definition once for the whole cluster.
