Hello,everyone.
 My name is H.Higuchi. I installed OpenBSD-2.2-i386.
 but I noticed a boot message which is something strange. that is,

#checking for core dump
#savecore: read;  Invalid argument

and I tried to type 'savecore -c', then she replied,
 #  savecore: read; Invalid argument
althogh I read man-'savecore', then tried
  'savecore -f /var/crash',
 the result was the same above or 
 #  savecore :write; Invalid argument

in addition to, the directry-/var/crash, has only minfree which
 is file .

And more worse, when machine boots, 
cron, or printer daemon came to say as,

#cron(or printer) ;savecore :read; Invalid argument

 I think this is what savecore should say is interrupting to cron's
message.
 help,me!
Y.S.
