Logs and Exceptions - V13 performance

Discussion created by Rajani on Nov 26, 2012

we have upgraded Clarity to version 13 few months ago and since then we are having very bad performance issues. Is there a way to find out who ran what portlet? Access and app logs are not providing enough info.
Also, we are seeing the following error a lot.

Exception was:
com.niku.union.web.WebException: com.niku.union.web.WebCacheException: org.xml.sax.SAXParseException: Attribute name "ndow" associated with an element type "action" must be followed by the ' = ' character.

Please update if any of you have seen this error and what does this mean?

Thank you,
