> Key: DISPATCH-1086
> URL: https://issues.apache.org/jira/browse/DISPATCH-1086
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 1.1.0
> Reporter: Keith Wall
> Priority: Major
>
> Whilst running performance tests against Enmasse, we periodically see a
> problem where Dispatch Router (1.1.0) goes into a state where fails to form
> TLS connections to the authservice. When this occurs, the router needs to be
> restarted to restore service. There does not seem to be a pattern to when the
> issue occurs, but in all cases where it has been seen, the test case included
> tens or hundreds of concurrently formed connections.
> The following message is written to the log:
>
> {noformat}
> 2018-07-06 10:38:45.543519 +0000 AUTHSERVICE (warning) Cannot initialise
> SSL{noformat}
> Unfortunately turning up the router logging (using the following command)
> reveal no more useful information. This Proton improvement JIRA was raised to
> include the diagnostics from OpenSSL.
