Boy did I discover that. Build a new kernel last Friday, cut way back
module/driver-wise booted it and got no errors and all the vservers were
running or at least appeared to be. Bad assumption that all erros show
up on the console. I'd left a module out that buggered Apache 2 but never
saw a message. Fortunately it was on a server doing gradus hosting for
some very low traffice sites.

I totally forgot to do this but I don't know that it would have mattered.
I think it was module that supported a module.

[error] (38)Function not implemented: Cannot create SSLMutex file

Well I backed down and got a running 2.4.25-vs1.27 kernel running ... so

Sam, Thanks for the tips. Next time I'll pay better attention and
follow them. :-)
