Hi,

It is not time-slider:

$ svcs -a | grep time-slider
disabled       Oct_25   svc:/application/time-slider/plugin:rsync
disabled       Oct_25   svc:/application/time-slider/plugin:zfs-send
disabled       16:24:29 svc:/application/time-slider:default
$ find /var/cache/fontconfig/ -type f | wc -l
545989
$ sleep 600
$ find /var/cache/fontconfig/ -type f | wc -l
548146

Thanks anyway.
Wil check other suggestions.

With best regards.
