FOSDEM 2015 - Autopsy of a multiserver deadlock in the HelenOS filesystem layer
Channel: Jakub Jermář
Date: 2015-03-03

A detailed walk through the analysis of a deadlock in the HelenOS filesystem layer involving IPC communication and spread across four server processes. The talk will focus on demonstrating how a problem like this can be root caused from within the same running HelenOS instance that was affected by it, relying solely on its own observability features.
