Hello, I'm using Rserve with Java and although it works OK for 50 or 60 requests, eventually Rserve simply stops responding and I have to force-quit and restart Rserve. During this time the JVM is fine and Tomcat (app server) is fine, too. The basic Java code does this: -------------------------------------------- 1. Create an R Connection 2. Execute an R Script via Rserve "eval" statements 3. Close the R Connection. I was going to use a memory profiler to see what was going on but Tomcat is not showing any Java-code memory leaks. Looking at the Rserve page, I see everything about the Rseve author...except for a way to contact him (unless I somehow missed that.) This may not be the correct R forum to ask this question, but I need to start somewhere. *** Note, in the past I've posted messages like this to the R developer forum only to be told that that programming forum is not the right forum as it's only for "pure" R programming *** Would appreciate any suggestions.

?maintainer
## i.e.
maintainer("rserve")
Also, please search. A web search on simply "rserve" brought up what
appeared to be many relevant hits.
Cheers,

Use the former if it exists - it is typically a URL. The latter is also given by maintainer("Rserve"). Or use utils::bug.report(package="Rserve") to make a bug report on the package. It uses the above logic to decide how to submit the report.

Hey Bert,
That's super helpful (maintainer ("rserve")). I had no idea. :)
So much good stuff right there in R.
I didn't find any relevant hits looking on the web for my particular
problem, but I'll email the maintainer.
Thanks very much.
