Re: Stratos Spinning Multiple Instances of the Already Active Cartridge

[Imesh Gunaratne]

Hi Manas,

I see several issues in the log, according to the below errors it seems
like the Stratos package you are using has not built properly.

TID: [0] [STRATOS] [2014-11-10 09:40:59,378] ERROR
{org.apache.stratos.autoscaler.client.cloud.controller.CloudControllerClient}
-  javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1791]
Message: elementGetText() function expects text only elment but
START_ELEMENT was encountered.

org.apache.stratos.autoscaler.client.cloud.controller.CloudControllerClient.spawnAnInstance(CloudControllerClient.java:162)

The above error has been raised while Autoscaler trying to communicate with
the Cloud Controller. Ideally an XML parser error should not be raised
here, unless the Cloud Controller service stub is not updated correctly.

TID: [0] [STRATOS] [2014-11-10 09:40:59,381] ERROR

This shows an error in the minimum rule drools file. May be there is a
syntax error in it.

Thanks
