shibd Memory Usage

[Andy Bennett]

Hi,

We're running Shibboleth SP 2.4.3 on Debian.

We tend to find that it likes to use a lot of RAM. I always assumed it
was just a function of the number of transactions. However, I've just
looked on one of our machines that doesn't actually do any Shibboleth
stuff but has the same configuration installed as our other machines.
It's been sitting there for 600 days or so and the logs show that all
it's been doing is downloading the metadata feed: it hasn't processed
any transactions. That shib was using some 700MiB of RAM.

Is that the amount that would be expected (given the size of the
ukfederation metadata of a few thousand entries) or is something amiss?
Is there any patches in newer versions that will reduce the memory
consumption?

We tend to find it takes at least 25% or 30% of the memory available on
a machine.



Regards,
@ndy
