Memory leak in SBT when compiling project

[Pavel Chlupáček]

Hi,

I do have project compromising of about 10 subprojects which all
have some dependencies on each other. When I hit compile for any of
subprojects the memory consumption of sbt increases with every compile
(irrelevant if it is with ~ or not). Eventuelly every compile will
increase memory of about 60 meg easily going to 4G in few compile
cycles when using ~.

I am quite confident this is memory leak of build process. Is there
any way how to aviod it // detect it?

sbt sbt 0.7.7 and Scala 2.7.7

project is agains Scala 2.8.1

Thanks for help

You could capture and analyze a memory dump. YourKit profiler has a trial version.

Do you actually get an OOME?

Yeah, though once I have migrated it dissapeared. I fixed it in sbt 7 by running GC more often. So probably tweaking gc intervals will solve it.
in the 0.10 I am not getting it when compiling, just some coleagues reporting this happening when running lift with jetty-run

Hello.

Can you please share your fix ?

I have the problem with sbt-0.10 and ~jetty-run.

Unfortunately, my knowledge of JVM internals is very limited and I cannot  tweak gc

Thank you!
