this is the log file where the memory usage by OVSD APplication SErver is stamped.
you can use this file to monitor the memory usage and whenever the memory usage hits certain amount of threshold, an alert can be configured so that the OVSD application server is restarted to be on a safer side.
I'm afraid I am not skilled in tuning Java but I know that giving it more memory via installservice.bat (bin directory) you can get better performance. This logmemory.txt would help you see the effects???
We currently have 2 Gig of RAM in our App server and have the following settings.
