log file getting too big

Hello, A bug report / feature request. I'm using the log "" command to log to a file. 1) The file seems to have a 2Gb limit on file size. 2) When the file gets to 2Gb, bird crashes. Can you make 1) use the large file things so it can be bigger than 2Gb, and can I suggest that 2) is not the right answer- the log file not being available seems like a really bad reason to bring down the entire network. Thanks, David
