I see the maximum size limit as being useful to avoid problems in error
situations where IOCs might start logging messages at a huge rate. At
least it avoids filling the disk. Note that if the limit is set to zero
then no truncation occurs (i.e. zero equals infinity).

Note also that the IOC log server now supports receipt of a SIGHUP
signal which causes it to execute the command supplied as the value of
the EPICS_IOC_LOG_FILE_COMMAND environment variable in order to
determine the directory part of the file name and then, if this is
different from what was already in use, to close the old one and open
the new one. We have a cron job which sends the signal at 5.30pm each
afternoon and places the new log file in a directory called
/xxxx/yy/mm/dd.
