-----------------------------------------------
Summary: Under high load propagation after pull might fail
Key: SYNCOPE-1241
URL: https://issues.apache.org/jira/browse/SYNCOPE-1241
Project: Syncope
Issue Type: Bug
Components: core
Affects Versions: 2.0.6
Reporter: Francesco Chicchiriccò
Assignee: Francesco Chicchiriccò
Fix For: 2.0.7, 2.1.0
The
[PriorityPropagationTaskExecutor|https://github.com/apache/syncope/blob/2_0_X/core/provisioning-java/src/main/java/org/apache/syncope/core/provisioning/java/propagation/PriorityPropagationTaskExecutor.java]
is designed to run the assigned PropagationTask instance via a
{{CompletionService}}, e.g. potentially in a separate thread.
Dach PropagationTask instance carries a reference to ExternalResource, and in
the end to the underlying JDBC connection (via OpenJPA); given what said above,
it might happen that a PropagationTask is executed in a different thread than
the one it was created in, resulting in errors as follows:
{code}

{code}
Such errors are observed especially when, as a result of a PullTask execution,
several PropagationTasks are generated and executed.
