I run systems using FreeBSD 9.0
FreeBSD utah.XXXXXXXcom 9.0-STABLE FreeBSD 9.0-STABLE #1: Wed Mar 21 15:22:14 MDT 2012 chad at underhill:/usr/obj/usr/src/sys/UNDERHILL-XEN amd64
and on those systems run a bunch of jails. I have Apache 2.2 built and running in the jail in question, and recently had need to add mod_fcgid to it. NOTE that the Apache and mod_fcgid were not installed through ports or packages. I download the source and build myself (for various reasons).
Apache inside the Jail, with mod_fcgid enabled will not start:
[Mon Jul 23 10:59:35 2012] [emerg] (78)Function not implemented: mod_fcgid: Can't create shared memory for size 1192488 bytes
I did a search on this and found that I would probably need a system kernel parameter changed from 0 -> 1
So I did that. (And restarted the jail). However, I still get the same error when trying to start apache.
I noticed a similar parameter security.jail.param.allow.sysvipc but cannot change this at run time and did not find anything useful about what this parameter is for using a search engine.
(As an aside, how would I change security.jail.sysvipc_allowed and also security.jail.param.allow.sysvipc at boot time? I added them both to /boot/loader.conf but they did not get changed at boot and I had to do the security.jail.sysvipc_allowed one again on the command line -- I have some vfs type kernel state variables set there and they stick)
I would appreciate some help with getting things set up so that I can run apache with mod_fcgid under my Jails on FBSD 9.
