nginx cache exceeded, cache manager busy

Our nginx -V outputs:

nginx: nginx version: nginx/1.0.0
nginx: built by gcc 4.1.2 20080704 (Red Hat 4.1.2-48)
nginx: TLS SNI support disabled
nginx: configure arguments:
--with-pcre=/home/ashtray/build_nginx/pcre-8.12
--add-module=/home/ashtray/build_nginx/ngx_cache_purge-1.2
--with-http_stub_status_module --with-http_ssl_module --with-debug
--prefix=/usr/local/nginx --with-http_realip_module

we have core dumps almost everyday, this happens from 0.8.15. We tried
to disable module cache_purge (but deleting the cached file outside of
nginx using rm when needed), and the worker still cores.
