So we know there are some issues with the current reporting.
Basically if anything goes wrong the reports come out incomplete.
On smaller machines with big datasets this happens sometimes (usually with the monthly reports). Additionally the pdf generation library we use is unreliable at best.

We have an ongoing 'new reports' project that simplify and streamline the report generation process that is more resilient and more performant. Additionally reports are being restructured to provide much more information and visibility into what is going on. All graphs will be supplemented with csv files should anyone want to do their own reports. Per user/host/email reports will be much more in depth to provide better visibility into user behavior.

All of this does come at a cost however. Instead of supplying shallow reports over both html and pdf; there will be deeper reports available only on the web. The emailed reports will be emailed links similar to quaratine digest emails. The schema will be completely different (affects those that have been doing customizations or custom reports on the schema). The report viewing interface will be totally different (much improved IMO).

You can expect all this in the 6.3 or 6.4 timeframe. In the meantime if report generation doesn't work for you the only option is to really add more hardware (better disks, more memory, etc). Hope that sheds some light on whats going on.
