I gathered some stats on Mon/Tue when mail-archives.a.o traffic was routed entirely to aurora.a.o (our EU mirror). This morning I installed current HEAD mod_mbox on eos, after flipping the DNS back yesterday, and graceful'd the server. Right now I see httpd processes with around 3GB memory in top, whereas in three different 'while sleep 5 && $i++ < 5000' samples taken prior to flipping the DNS I see exactly one process having exceeded 1600MB memory (to 1613MB). I'm not aware of differences other than flipping the DNS and upgrading the mod_mbox version to include the last week's fixes.
