Recording waveform variation

I seem to have an intermittent problem recording into Audacity. Scenario is that I record first side of vinyl album. This works fine. When I change album side the right hand channel doesn't record, even though I haven't pressed pause, merely turned the album and continued recording. On the attached image you can see the waveform stops recording the right at about 21 minutes. When I retried at the end, it recorded correctly (40 minutes on waveform). Can anyone shed some light? Cheers.

Since you didn't hit pause or make any other change in Audacity, my guess is that your headshell on the turntable is loose or otherwise intermittent.

I have had this same problem intermittently, however the LP will play fine on an separate analog stereo, while I am recording it on audacity.

Thanks for the replies. I have checked the fittings and nothing feels loose.
Cliff, are you saying that your recording are fine in spite of the Waveform pattern. I can notice it on mine when I play it back.
The reason I am so fixated on this is I am undertaking a major project to digitalize my entire record collection (I am about 100 into 400 records) and I don't want to be repeating a mistake.
I am going to try trying taping from a different source (an Ion Tape Express) and reinstall Audacity if the problem persists.
It's the intermittent nature that make it such an issue. Sometimes it works fine for a session of taping, other times you tape one side of an album and the problem occurs.
Thanks again. I'll let you know how it goes.

I am not quite sure I understand what asking, however this problem does occur on several different inputs to the amplifier. (I still get stereo on the computer speakers when this problem is occurring).
