Geert Bevin resolved CDV-658.
-----------------------------
Fixed In Revision: 7581
Resolution: Fixed
I committed some changes that should fix this. I can't however verify since I
couldn't see this behavior on my linux installation.
> server hangs at startup (linux)

> Key: CDV-658
> URL: https://jira.terracotta.org/jira//browse/CDV-658
> Project: Community Development
> Issue Type: Bug
> Components: DSO:L2
> Reporter: Tim Eck
> Assignee: Issue Review Board
>
> I'm pretty sure this issue is new with the updated version of jetty, but it
> could also be some of the new stuff we're doing with jetty (as opposed to the
> jetty version)
> On linux, SecureRandom looks like it reads /dev/random which can block if
> there is not enough entropy in the system. The server can be stuck here (see
> stack below) for quite a while (ie. more than 10 seconds). If we can avoid
> this code path, we probably should (maybe this means disabling sessions
> somehow?)
