never saw that before but the server definitely loads data when an agent connects (mainly its the agent condition cache stuff). Definitely get a heap dump and see what's using all the heap. That would help pinpoint where we'd have to look. On 01/07/2011 02:57 PM, Bala Nair wrote:

I think we recently converted most (possibly all) places that access package bits to using streams rather than copying the all of the bits into memory. However, there may still be a few places that copy into memory. Are you using RHQ at all for installing/deploying large packages?

Ok, that at least rules out that possibility. Your setup does not sound too extreme, so there could be a heap leak somewhere. Once we have a heap dump, we should be able to figure out if that's the case. Once you have one, let us know, and we'll figure out some way for you to get it to us.

No, all our metrics are measurements or traits. On 1/10/11 4:35 AM, Heiko W.Rupp wrote:
