Subject Re: Add refactor engine in enhancer/bundlelist
Date Thu, 01 Mar 2012 23:20:26 GMT
Hi Alberto

I spent some time to look into "Build failed in Jenkins: stanbol-trunk-1.6 #772"

The most interesting file is the error.log file of the Stanbol
instance used for the integration test.

For the first view calls to the enhancer everything looks fine (~5sec
for the Refactor engine).

But later - after time code "01.03.2012 19:49:21.04" (use this to
search in the file) something starts to went wrong with Jena TDB.

[Thread-36] >> seo_refactoring  and
[Thread-12] >> looks like a Jena TDB demon

are the only active one (looks a little like a deadlock).

You can safely ignore the [DataFileTrackingDaemon] this checks only
every 5sec for Resources of the DataFIleProvider.

I have really no idea what is going on here. Maybe you can make more
sense of this
