SubjectOops in 2.1.35 w/o SMP=1
Date

Here is an oops I just had; looking back through the logs there's more,
all caused by sendmail. The computer is Redhat 4.0, a tyan dual pentium w/
only one cpu installed, 32 meg (good quality) ram, IDE disk, Realtek PCI
Ethernet. This is 2.1.35 compiled with the SMP=1 commented out, as this
causes my machine to go into an endless series of crashing oopses.

Running sendmail will cause an oops like this reliably, at the same address
&c. (e.g. "mail root" will cause this in about a minute). 2.1.31 did not
have this problem, I couldn't compile 2.1.34, and haven't got around to
checking 2.1.3[23].

And the ksymoopsed thingy ...
