The latest 2.9.12 dev release does have improvements in thread safe of the pager, but you have to really thrash it to see these problems in older versions of the OSG so I'd guess that 2.8.4 is probably fine. There won't be any harm in trying 2.9.12 out though is pretty API compatible. As for your specific problems, the OSG itself doesn't use shared memory at all, and doesn't use any clever memory tricks so should just operate independantly from Qt and what ever it does on the memory front. The exception to this would be if Qt itself is reimplementing malloc/free and new/delete in which case you really have to look at Qt for tracking down what the problem is. My guess is that use of paged databases on the OSG isn't directly the problem, rather it might just be stressing the system more such that eixsting problems in other codes are brought to the fore, so it's as much just a coincedence rather than direct cause and effect.
