I am having some trouble with our AOLserver setup. It crashes
frequently under extremely light load. Below is the backtrace. It
appears that something in libc6 (gethostbyname) or oci (OCIServerAttach)
is causing the problem, in particular when ns_db tries to open a new
connection to Oracle.
Has anybody encountered this, or can make better sense of this backtrace
them I can?
