## Package stdout/stderr size limit
|
||||
|
||||
The possible issue of output logs filling up disk space is addressed with a
|
||||
"log\_limit" config option. By default, if the output log file reaches the
|
||||
limit, the compilation output is no longer logged to file in the logs dir.
|
||||
|
||||
Change "log\_limit" in the config to a value in bytes if the default of 1 GiB
|
||||
is too little for your use case (if the size of your output logs extend past 1
|
||||
GiB somehow).
