Below is from Kokua Ticket #349.
Reports from several sources that Kokua crashes after a short while of operation on Avination Grid are confirmed. These crashes are actually excessive memory leaks that are related to HTTP Texture pipe lining as implemented in Kokua and its interaction with Avination servers. With Develop->HTTP Textures, debug setting httpPipelining, unchecked Kokua operates correctly and doesn’t crash. Avination gird is the only grid known to have this problem. As such the work around for Avination users is to un-check Develop->HTTP Textures or set the httpPipelining debug setting to FALSE.
Testing was on Windows. Request users of other platforms test and comment about results in the ticket which is linked above.
