It is definitely not a memory leak.
Everything you describe except the crashes are normal. The ePubs that take forever inevitably have their origin as a MS Word doc that was saved as html without being filtered. We are aware of these and they don't have a history of crashing, just taking forever to complete. Some have reported 24 hours, the longest I've seen is 6-7 hours.

Increasing memory is normal for conversions the longer they take.

I think I am observing a repeatable bug but will revise my view if others are not seeing it.

I am also running calibre 0.7.45 on Win XP dual core system. I just converted 300 ePubs to Mobi without incident.
I have the following settings
Waiting worker processes : 4
Job Priority : Low
Calibre library exempted from Anti-virus scanning.
Calibre configuration folder exempted from A/V scanning.
I believe the problems you're experiencing are unique to your system. Look at what other programs/processes are running. Did you add anything new to the startup in the last 3 months?
Sorry I couldn't be of more help.
