Hi Justin,

Yes, that could be it. Panda boards have 1GB of RAM, and Clang objects
are getting big.

Galina, do you have some kind of swap on that board? I know swapping
on USB is not great, but at least it stops the bot from dying every
few builds.

cheers,

Hi Renato,

There is swap on each board and I'm not aware of it's going anywhere
close
to the end.

KiB Mem:   1003948 total,   637868 used,   366080 free,     9788 buffers
KiB Swap:   524284 total,    13836 used,   510448 free.   183144 cached Mem

$ swapon -s
Filename                                Type            Size    Used
Priority
/swapfile                               file            524284  13836   -1

I'll take one of the boards off and see if I could get the issue in some
reproducible form.

Thanks

Galina

Doesn't seem like it... :/
