Dear R-developers,Some of the more fat scripts (50+ GB mem used by R) that I am running, when they finish they do quit with q("no", status=0) Quite often it happens that there is an extra stderr output produced at the very end which looks like this: Warning message: In .Internal(quit(save, status, runLast)) : system call failed: Cannot allocate memory Is there any way to avoid this kind of warnings? I am using stderr output for detecting failures in scripts and this warning is a false positive of a failure. Maybe quit function could wait little bit longer trying to allocate before it raises this warning?
I don't know what waiting would accomplish. Generally speaking the allocation functions in R will try garbage collection before failing, so it looks like you are in a situation where there really is no memory available. (I think code can prevent gc; maybe your code is doing that and not re-enabling it?)
Having a reproducible example would help, but I imagine it's not easy to put one together.
