Simulation of Oscillator Does Not Stop

Hi I am trying to simulate the rather simple oscillator circuit below:

The simulation runs if I make R1 680k. It does not oscillate. I tried to change R1 to 100k as indicated above.

However, the simulation just keeps on running. It does make the following recommendations though:

I however cannot find PTRANABSTOL or PTRANVNTOL anywhere.

Please help.

Regards,

Deon.
