Yep!

for reference, inex's cache flushes take ~2-3 seconds. It may be
happening that you're i/o bound on your RRD spool disk. If you have
cache flushes which take longer to run than the flush timeout, for sure
this would cause problems. What's the i/o load looking like on the
disk? Assuming your partition is /dev/sda$something, e.g.<br>
<br>
# iostat --dec=0 -y sda 1 | grep --line-buffered sda<br>
<br>
The first column will give TPS with 1s granularity.<br>

Reloading the mac table should be pretty quick. This is just a
structured dump of an SQL query.<br>
