Exceptions using designer

calca Aug 2, 2013 2:18 PM

Hi Guys.

I am using the latest snapshot of designer in guvnor-integration branch, it is 2.5-SNAPSHOT, and guvnor 5.4.

Designer works well, but after some time using it and opening processes, it seems to be slow, and log many lines like the following,

[org.apache.jackrabbit.core.ItemManager] (http--127.0.0.1-8080-23) overwriting cached item 976535bd-6ec8-4473-9991-febc180fe7e7/{http://www.jboss.org/d

rools-repository/1.0}versionNumber

and then, it starts failing.

I tried changing the 5 seconds timeouts in designer code (originally is 5 seconds), but in one point it seems to be too slow and start failing.

Does anyone have experienced this and knows what can I check in designer to fix it?

THanks

Designer communicates with Guvnor 5.x over the Guvnor REST api. This looks like an issue with that rather than to do with Designer.

Yeah, but it happens specifically when using the designer. But well, for some reason after working only with designer inside guvnor, it starts failing there. We could reproduce it quite easily by opening like 6 or 7 processes..

Thanks
