[Buildbot-devel] Buildbot through stacktrace during SVNPoller

[William Deegan]

Fulvio,

The machine is running buildbot + svn + a few nx hosts.
The startup in question doesn't have a lot of hardware and will likely be migrating everything but svn off of that machine in the near term.
It's centos 5.5 64 bit linux.

Buildbot's eating ~1GB
SVN+ Subversion edge (activestate) eating another 1GB
So that doesn't leave a whole lot for the rest.
16GB should be sufficient.
