Try 'mythbackend -v most'
This disables database query logging and timestamping which can add
overhead, but the former may be useful if it is a particular query
which is causing the problem.
Which capture card(s) are you using?
I'd also recommend thinking about running memtest to check your system
memory, lmsensors to monitor your CPU temps, and using SMART to
monitor your drive health. Looking in the syslog whenever the
mythbackend process dies may also reveal extra information.
Did you reinstall from scratch after replacing the faulty hardware components?
