Nginx 1.2.1 won't start with large CRL

Server NGINX
1

I have a CRL loaded into ssl_crl variable in the config file that’s
about 256MB in size and nginx won’t start. I get the following error:

nginx: [emerg] fork() failed (12: Cannot allocate memory)

I believe this is due to nginx trying to load the file into memory and
it’s bombing. It maxes out my server’s RAM and then just crashes.

I would rather rewrite the subject as “nginx won’t start if there
isn’t enough memory”. It won’t. Try adding more memory and/or
find a way to keep your CRL small.

The CRL cannot get any smaller as it’s a DoD CRL. Also adding more
memory
does not solve the problem. It seems to have an issue with starting the
server period with a large CRL.
