I just got my ASI2600MC.
Had 4 successful sessions with INDI running on RPI4 (latest SM stable) and KStars/Ekos on Windows client.
Tonight, however, I ran into this very problem.
Running everything on RPI4.
After 2-3 frames it crashes consistently with a "unable to allocate memory for temporary bayer buffer: std::bad_alloc" message

I've been having horrible results with EKOS and my ASI2600MC for over a year. I keep hoping software updates will fix it, but all of my imaging sessions are ruined by the PI crashing. I have un-selected debayering in EKOS FITS setup, and it still crashes. Sometimes after taking one frame, sometimes after taking a few.
Very frustrating... I had a ticket opened about this a while back, and some beta fixes were loaded onto my Stellarmate, but it didn't really help.
You've tried to help me too a number of times over the past year with the exact same issue with ASI2600MC Pro. Unfortunately still not working here either, always random crashes still - from the debayer error to Kstars just crashing and restarting after a sub is attempted. It's strange that it all appears so random. Same now too on this latest version - upgraded from new image of recently downloaded 1.5.9 -> 1.6.0 w/KStars Stable release 2021-9-30 (rpi4 8gb)
I wish I could get this to work for me. Any hints?
