A memory leak would be consistently--though admittedly only temporarily--cured by a reboot. Is that what people are seeing? The descriptions posted here make me think people find themselves confronting a problem not so easily worked around.

It would fit with geneven not running across the problem though. He'd be resetting the clock on the memory leak every time he swaps batteries.

In contrast though, I reboot less often than once a month, and I haven't had my N900 forget it has a SIM. Of course, I also make or receive a call on my N900 less often than once a month, so if there's a memory leak caused calling, I'm unlikely to see it.

That's a whole lot of every which way. Are people finding that rebooting (or perhaps even power off + pulling the battery) always fixes the problem, at least temporarily?
