Hi,

Can you please share the exact API calls you used to reproduce the issue?

Thanks!

[Dev] API Manager - periodic failure of OAuth2Service for AccessTokens via the publisher API

2016-09-19 Thread Alan Tucker Spida Solutions 
We are periodically seeing failures when trying to request Access Tokens via 
the APIM publisher API. An instance of APIM will perform correctly returning 
AccessTokens for a time. Occasionally, after restart it will fail when 
requesting access tokens via the publisher API. After subsequent restarts the 
same instance may or may not then return to operating correctly. The test 
scenario in all cases is the same.

Note that if the user (that is being used to request an access token) logs into 
the API store of the APIM instance, subsequent requests via the Publisher API 
will then succeed. This appears to be reproducible.

On failure the typical stack trace below is seen:

[2016-09-19 09:52:31,163]  INFO - TokenMgtDAO Thread pool size for session 
persistent consumer : 100
[2016-09-19 09:52:31,262]  INFO - OAuthServerConfiguration The default OAuth 
token issuer will be used. No custom token generator is set.
[2016-09-19 09:52:31,263]  INFO - OAuthServerConfiguration The default Identity 
OAuth token issuer will be used. No custom token generator is set.
[2016-09-19 09:52:33,516]  WARN - AccessConfiguration Error loading properties 
from file: access-log.properties
[2016-09-19 09:52:33,594]  INFO - TimeoutHandler This engine will expire all 
callbacks after : 120 seconds, irrespective of the timeout action, after the 
specified or optional timeout
[2016-09-19 09:52:33,798] ERROR - OAuth2Service Error occurred while issuing 
the access token for Client ID : ***, User ID
