Problems with Jail hanging

[Konrad Neuwirth]

Hello everyone,

we're facing a strange problem that I do not really know how to debug, either. We're running a system under 

DragonFly v3.1.0.159.g79580b-DEVELOPMENT (X86_64_GENERIC)

and set up a jail for a web server on it ? following the steps outlined in the Handbook. 

Now, starting apache with a medium load and a good number of virtual sites there leads to a lockup ? not just of the apache process or the jail, but the entire system. Only a hard reset helps. 

If that has any relevance, we're running apache 2.2 from pkgsrc, compiled with the following options: 

PKG_OPTIONS.apache+=suexec apache-mpm-prefork

So then ? how can I go about getting the jail setup to run? 

Thank you!
