But don't know what sort of jpegs the Sony camera saves. Anyhow I've also now resaved them as png (about twice the size).

The set up of this machine is identical (as far as possible) with another happy machine. The difference is different hardware (such as NIC hardware and CPU) and that this is running PAE and the other AMD64. I know that introduces a lot of different code, so it may not be a useful comparison. Another data point is that we switched the scheduler ('sleep queue' sounds vaguely like something scheduler related to us) from 4BSD to ULE with no change in behaviour. This is starting to cause us some grief with this machine offline, so we might need to throw some new hardware at the problem and hope the issue goes away. I am just afraid that the problem might follow us if the issue is rooted in our setup rather than the hardware choices.
