Premiere struggling with big exports, puts audio glitches into the export

I'm working on a 52 minute show for tv. Yesterday I spent all day trying to export, and was met with a myriad of issues. First I tried exporting natively out of Premiere (export setting MXF OP1a XDCam50 59.94), I have a 128 gig memory computer and with probably 44 seconds left into the export, Premiere told me my computer was out of Memory (and I didnt have any other apps open). I find that surprising that a 128gb ram computer can't handle an MXF export that will only be 20 gb large when done. Since Premiere couldn't natively handle the big export, I queued it in Media Encoder. No memory issues there, but when I took the final MXF and brought it back into PRemiere to QC it, segment 5 had this really bizaare audio glitch. It's almost as if media encoder took a random patch of audio and put it at 52 minutes in. So now all of a sudden this small patch of audio is out of sync and goes back into sync a moment later. (This audio glitch isnt the same audio glitch that I described in another post where I believe the issue is stemming from exponential fades nested in a 59.94 sequence, because with that issue i was hearing the audio glitch on the nested timeline. In this latest "big export" issue, I'm only hearing the issue on the exported MXF, and not on the raw timeline ).  Restarted the computer. Then I tried again a 2nd time, same issue but now the audio glitch is in a slightly different place on the export. Seems arbitrary. So then I took 2 bad MXF's and merged the non-bad parts together on the timeline and exported it (cant remember if it was through premiere or media encoder) and that export had an audio glitch in it that wasnt on the timeline. I told my co-editor about this and he goes yeah I've had problems too exporting big shows. (So I'm pretty sure the issue isnt just with me). The only way I was able to make the audio glitches stop showing up in my exports was doing this: Export Segment 1 as a separate MXF through Premiere not encoder (same with segments 2 through 5, individual MXF exports). So now we have 5 separate MXF's. Bring those back into premiere, put all 5 MXFs on one timeline and export it as one giant MXF. So essentially baking separate parts of the timeline was the work around. But it's an extra step. I'm hoping Adobe can look into this and maybe fix it?

All the footage is 1080. 5-6 cameras stacked on top of each other. (Mxf footage says video codec ai13.  Camera #6 ronin is mp4 codec H.264). A lot of the footage has the "colorista" filter on it.
