[comp.sys.sun] Problem about OS 4.1

yhsieh@uunet.uu.net (11/21/90)

We have a Sparc Station running OS 4.1.  It is up for a long time, but
suddently we can't rlogin and do anything on that machine.  The error
message is like this :

ld.so: call to undefined procedure __flsbuf from 0x6184 

Does anyone have any ideas about this kind of error ?  Thanks a lot.
