Terracotta Discussion Forums

Hi, everyone.
I`m trying to start Terracotta Server on openvz debian amd64 container. It`s giving me this:
Code:

What could possibly be wrong?

Hi ,

Can you please share details about your use case , configuration and client/server logs .

Sure. Config and logs attached. Use case: I have several Hibernate-powered apps, want to use Ehcache as L2C, each app is distributed, so, since cache names are the same for every app (they are simply entity names) I guess I need separate Server Array per app. I use openvz virtualization, so I thought it`d be nice to be able to run tc server in a container.

Allright, seems I`ve got it. Besides 'ulimit' limits openvz also has 'user-beancounters' limits. I had the default 260 value for 'numproc' in my container - turns out Terracotta Server needs more. As a rule of thumb - if something fails complaining on any resource shortage - check /proc/user_beancounters.
