First thing to check is your timing. I use a symmetric 6-phase approach where you have overlap on the 3 groups of cathodes. Secondly, you might need a bit more voltage-drop at the cathode resistors (ie, make them slightly higher value).
I had this problem with my homebrew A101 spinner, and once I had about 30 volts across the cathode resistors it continues to run flawlessly after nearly 8 years of continuous operation.
