IdP stopping metadata retrieval

[Martin Haase]

Hi,
this happened on two schools we support, one with 2.3.6 and one with
2.4.0. The IdPs were otherwise healthy and working for months, but
stopped to retrieve metadata for 3 different URLs at the same time.
Environment is CentOS 5, Tomcat 6 prepped by Apache2.2. The two schools
are in separate net segments. The 2.4.0 school is a terracotta-cluster
of two, here only one instance is affected. Pretty default configuration
for FileBackedHTTPMetadataProvider. The metadata signing certs are still
valid. When I restarted Tomcat, metadata were fetched fresh again.
I can only see one suspicious item: The time stamps of the metadata
backup files was Nov 4. At that time, I see in the logs that one
metadata source was unavailable temporarily, "Error retrieving
metadata". After that time, I cannot grep any occurences of "metadata"
in the process log.
Do you have an idea?
Cheers,
Martin
