No, it seems I get fewer gaps using --no-cache, but it has always only affected the "cpu" and "users and processes" graphs. When I can catch the missing data in process, I see that the rrd is never updated or timestamped, but I never see any type of error message in any of the log files.
I also forget to mention that I am only using one setting for the rrd definitions and I do have the extra-rrd definition for the soloris MP and Zone stats.
Here is what the configuration file looks like for the rrd... stuff in tasks.cfg.
"rrdstatus" updates RRD files with information that arrives as "status" messages.
[rrdstatus] ENVFILE /home/xymon/server/etc/xymonserver.cfg NEEDS xymond CMD xymond_channel --channel=status --log=$XYMONSERVERLOGS/rrd-status.log xymond_rrd --no-cache --rrddir=$XYMONVAR/rrd
"rrddata" updates RRD files with information that arrives as "data" messages.
[rrddata] ENVFILE /home/xymon/server/etc/xymonserver.cfg NEEDS xymond CMD xymond_channel --channel=data --log=$XYMONSERVERLOGS/rrd-data.log xymond_rrd --no-cache --rrddir=$XYMONVAR/rrd --extra-te sts=mpstat,zonestat --extra-script=/home/xymon/server/ext/rrd_data.pl
And here is the rrddefinitions.cfg file for only what I have changed.
This one is the default setup. You can change it, if you like.
[] # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg. RRA:AVERAGE:0.5:1:82944 # 576 datapoints w/ 6*5 minute averaged = 12 days @ 5 min avg. #RRA:AVERAGE:0.5:6:82944 **** NOT USED **** # 576 datapoints w/ 24*5 minute averaged = 48 days @ 5 min avg. #RRA:AVERAGE:0.5:24:82944 **** NOT USED **** # 576 datapoints w/ 288*5 minute averaged = 576 days @ 5 min avg. #RRA:AVERAGE:0.5:288:82944 **** NOT USED ****

Tom, do you get the same as me with the "--no-cache" option:
- gaps for most trend graphs go away
- trend graphs for "cpu" and "users and processes" went to zero (actually NaN)

I put a note in last week saying I was having the same issue in the 4.3 release and looks like the same issue that was in the beta. The holes are totally random and I asked if the --no-cache still works the same in the xymond_rrd, but I have not seen anyone respond.

Has anyone made progress with this? I have the exact same problem with no solution and nothing interesting in the logs. As soon as I disable caching on xymond_rrd, the gaps go away.
However as soon as I did this, the graphs for "cpu load" and "users and processes" both stopped updating completely. All other trend graphs are perfect. None of the network tests had a problem, so this seems to be restricted to numbers coming from the xymon client as "client data".

I believe Henrik has found and fixed this issue, but I don't know if it is in the beta3 version. He has been talking about a new release.
