That email from Shawn today with the subject "Re: [Fed-Talk] Mac
Ownership & Permissions (UNCLASSIFIED)". Anything from Tim Miller
(Sorry Tim.. ;-) ) and a few others. This is with Apple Mail on
10.4.10. Nothing else is special about the system unless you count
all the developer stuff from Apple that has been installed.
Ok. I did some digging and using those superpowers that Activity
Monitor grants me, the culprit seems to be 'ocspd', which when I
tried to view a signed email that was on this list a few days ago,
the memory spiked to 800MB and locked up the GUI for about 30
seconds. Is this normal?

That really can't be answered without knowing more information:
1. How big are the e-mails and/or the data contained in them?
2. Are the e-mails self signed or are they checked against a public
key?
3. Is this custom software as in that provided in a package developed
for you or is it off the shelf with no modification.
4. Is this happening on all signed e-mails or just some of them?
5. Do you know what type of signing algorithms are being used?
If they're simple text e-mails and everything is off the shelf, I
would think you might want to assume this is some type of OS bug.
If the e-mails contain data such as images or reports of any type,
then it means the e-mail and every byte of data in the included
documents or images is likely being hashed through a signing
algorithm to check its validity. This can be pretty memory and CPU
intensive, but I have to admit unless this is being done to mega-
documents or mega-images, eating up 700M sounds pretty inefficient.
I would need more information to even hazard a guess.

Why does my computer (Mac Book Pro, 2GB Ram, 160GB Drive) seem to
lock up and the memory usage spike ( to about 700MB) every time I
try to view a signed email? This is getting to the point where I
am about to put a filter to just delete anything from those
people I know sign their emails.. just getting frustrating.
This is with OS X 10.4.10. There is always lots of Ram available
when this happens as I monitor it with a utility constantly. The
same thing happens with Safari when I log into the US Air Force
Web Mail site with my CAC.
Thanks for any help.
