Thanks for the detail, Leszek. There could be something causing increased occurrences of a conflict (race condition, etc). Could you look in mod_auth_cas's cookie directory to find the '77a947d79339d3373937985aa1610fgr' file (or whatever ID is currently causing errors), and send the contents? This is a long-standing bug that we have not manage to isolate, so while I do not have a solution for you, I am interested in samples.
Also, for full disclosure, I have recently joined Red Hat as a Solution Architect, and GlusterFS has been acquired by Red Hat (rebranded as Red Hat Storage), but I have not yet spent any time working with it.
