SUMMARY: /core from login?

From: George McClintock (

Our SPARC Server 1000, Solaris2.3, with the recommended patches, and
which runs httpd and gopherd as well as supports many users, dumped
core in /. My indiscrete query encouraged few responses. My humble
apologies... Now, the nightmare continues.

One respondant reported:
> I am not sure what causes this. But it happens once or twice per day

> The SuperSparc processor has more stringent data alignment
> requirements that seem to cause this.

We received the 2.4 11/94 upgrade and installed it including the
patches on the CD. Now, all new users are denied access to the
machine for the first 3 to 20 attempts both remote and at the console.
The telltale sign that a user has correctly typed her password is the
error message: "Login incorrect" and a broken connection. Eventually
the user gains access. (If the user mistypes her password, she is
prompted to login again.) And this in a default Solaris2.4
environment, without C2 or tcp wrappers.

SUN replaced the motherboard and the 2nd SCSI bus/ethernet card. No change.

With Solaris 2.3, the login/password problem occurred, but usually
dumped core. 2.4 hasn't core dumped yet, but the machine is virtually
inaccessible, with 300-500 students arriving in 2 weeks.

Any suggestions will be greatly appreciated.
