Just as an update I upgraded to latest NVidia drivers and flash has become much less stable. Strace of the npviewer system showed a lots of time outs with resource unavailable - just checked my dmesg and found this:
npviewer.bin[10573]: segfault at 418 ip 00000000f60c4d36 sp 00000000ffeb8748 error 6 in libflashplayer.so[f5e57000+b5f000]
