The size of the ide.log file is checked during the
start of the IDE and if it is larger then a limit
the file is renamed and configured number of old
files is hold for some time.
This does not work in case of excessive logging
during the running IDE. In issue 29802 user
reported ide.log file of size 96MB! This should
not happen. The size of the file should be checked
during the writing into the file. The excessive
logging is not good, but platform should manage it
Be certain that a large log file is preferred ofer lots of little log
files. Much faster to delete (at least on windows) 1 giant log file
than 2 1/2 giant log
Of course I assume at some point you start deleting old logs?
