We have an oracle 8.1.0.5 instance over sun solaris, during a hard user deletetion instance crashed, and during startup this is what always happens (down):

From oracle metalink lookup SIGSEGV is a segmentation error. What can we do, except calling oracle ?
The instance version should be desupported. Thanks for any suggestion.
