Launching Mail becomes a runaway process and creates a massive memory leak in the kernel task

Question

I have 16gig of ram, my kernel task is currently using 12gig, Mail is no longer responding while using all remaining ram
Mail has been jammed at 100% of one i7 core for about 2 hours now, disk activity is almost nonexistant.
it was running poorly yesterday, rebuilding the mailboxes did not yeild a positive effect
permissions and drive check out
Quicklook is also reporting a lot of bs when finder windows are open:
example:
10/26/13 1:40:20.985 PM quicklookd[14056]: Warning: Cache image returned by the server has size range covering all valid image sizes. Binding: VariantBinding [0x603] flags: 0x8 binding: FileInfoBinding [0x503] - extension: mp3, UTI: public.mp3, fileType: ???? request size:32 scale: 1
I hate the new activity monitor so much, none the less, "Memory Pressure" is pinned
Seeing a whole lot of this in the console as well:
10/26/13 2:57:11.000 AM kernel[0]: SMC::smcReadKeyAction ERROR TM6P kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff802ba32000

Answer 1

I feel your pain!
Mac Pro with 32 GB, and Mail takes about 5 minutes to "start" - well, show the Mail Menu. Then, another few minutes to actually draw the window... but wait, it STILL needs more time to actually show the accounts and mail.
The (stupid) new Activity Monitor show Mail using 12 GB of RAM, and several com plist files also sucking up CPU time and RAM. Why Apple has to dumb-down good information to "Memory Pressure" is beyond me!
I have reported thsi to Apple, and they had a Support person get in touch with me. I have sent several spindumps and tarball files last week, but no reply. Today, I pinged the support person who said Apple Engineering was reviewing the information, and would likely get back sometime as *maybe* some others were experiencing this problem...
