Ya - Drupal caching was on..
I've turned-of several memory hogging and SQL pounding modules in Drupal which has improved things even more.
and, FYI - when the site was crashing, CPU usage was reguarly hitting 70%-85% for extended periods of time, and memory usage was regularly at 78%-90% ..
NOW, after upgrading to 2gb ram and removing those extra modules in Drupal CPU is usually around 1%-3% (i've seen it peak shortly at 20%) - but it's now rare that I've seen it go over 10% ... memory usage is now around 38%, and rarely goes over 50% ..
