When closing most of the running programs on that machine, it usually works again for some time. I assume this happens because of memory fragmentation? What can I do against this error, except just rebooting the whole machine every time and closing applications all the time?

Yes, fragmentation is likely the cause. Adding Microsoft people who might know how to prevent this, since I don't. ^ permalink raw reply [flat|nested] 4+ messages in thread

I am currently trying to reproduce the problem, but until now it just happens randomly after some longer uptime. I will send traces as soon as I can reproduce the error.
