Subject Re: Sonar instance ETA
Date Tue, 22 Feb 2011 12:36:58 GMT
Some final changes:
- switched to -XX:+UseCompressedOops on the builds and servers to constrain memory some more
and avoid swapping
- increased ulimit -n on jenkins

I'll watch it a couple of days and push all this to the wiki.

all the projects are building now, but we should monitor it to see how stable the main sonar
instance remains.
