[Camino-users] Can't load log handler "java.util.logging.FileHandler"

[Damien McHugh]

Hi all,

I've been running a batch of simulations using mesh substrates, and some of the runs give the following message:

Can't load log handler "java.util.logging.FileHandler"
java.io.IOException: Couldn't get lock for %h/CaminoRuntimeLog%u.log

The simulations appear to run ok after this message, with the usual:

17-Feb-2013 00:44:52 simulation.dynamics.StepGeneratorFactory getStepGenerator
INFO: instantiating fixed length step generator
17-Feb-2013 00:44:53 simulation.geometry.substrates.MeshSubstrate <init> ...etc

coming next. Any idea what the log handler message is about?

Many thanks,
Damien
