Lighttpd

It appears that during graceful restarts where the old lighttpd takes some time to spin down, the new lighttpd's updates of rrd data can cause an rrdtool error:

2005-12-18 06:28:00: (mod_rrdtool.c.410) rrdtool-response: update /path/to/rrd/lighttpd.rrd N:5876:138222:23
 ERROR: illegal attempt to update using time 1134887281 when last update time is 1134887281 (minimum one second step)
OK u:0.00 s:0.00 r:29.41 
2005-12-18 06:28:00: (server.c.900) one of the triggers failed 

This error does not occur under normal restarts, only when two lighttpd processes are running (one waiting for existing connections to close, the other accepting new connections). After the error, the new lighttpd process does not log further rrd data.

Is there any workaround? Is it possible to have same-second updates of the rrd database treated as a soft failure and logged, but not stop future updates? As you might imagine, the combination of rrd and graceful restarts are very desirable to have working in combination on systems under heavy load. :)

Thanks,
James
