Subject Fw: Hermes Run (was Re: Missing Documentation)
Date Tue, 04 May 2004 21:29:15 GMT

I don't know how aware you are (if at all) the Python Gump uses Forrest to
convert xdocs (and SVGs) that represent it's run, into a site. This link is
on one site, and references others:

The Python code generates the XML, then launches forrest (pretty recent
versions) against that.

Unfortunately there are times when forrest just goes wacky, it's memory
usage grows unbelievably & it bogs down to a crawl. I'm not sure if this is
an obvious leak, or some sort of garbage collector confusion, or what.
Unfortunately it isn't easily reproducible (although it might be on right now). I think it comes when given a certain number
of artefacts to produce (where that number is quite large, few thousand.)

Does anybody have any thoughts on Forrest tuning, or tracing, or whatever to
attempt to dig into and/or resolve this problem?

Thanks in advance.
