Hi,
This morning I'm hitting OutOfMemory exceptions on some really trivial
code, and it's all coming from either AppStats or logging:
Uncaught exception from servlet

Is anyone else having any issues? It could well be that I just haven't run
this code since the change to the new instance sizing...
Cheers,
Simon
