[Nagiosplug-help] check_http

[Brian Smith]

Has anyone seen this message or know why it happens on my apache-ssl 
servers:

./check_http -S -H www.domain.com -v
SSL seeding OK
2137:error:140820A7:SSL routines:SSL3_CHECK_CERT_AND_ALGORITHM:missing 
export tmp rsa key:s3clnt.c:1952:

There is no problem with lynx or curl or in a web browser, just the 
check_http plugin.
The Webserver is Debian running apache2
