#234: rrdcached dies when journal reaches 2G
 Reporter:  human      |       Owner:  oetiker
     Type:  defect     |      Status:  new
 Priority:  major      |   Milestone:
Component:  misc       |     Version:  1.4dev
 Keywords:  rrdcached  |

 When running rrdcached with -j, -f 14400, and -w 7200, the journal file
 reaches 2G which causes rrdcached to exit.   We chose these parameters to
 cache two hours of updates before starting the write cycle for 400k rrds.
 Trying to run with -f 7200 -w 7200 produced a warning that -f should be at
 least 2x -w.
