From 608f56ab82800980ee5158c75bc9b8993f5f0c8c Mon Sep 17 00:00:00 2001 From: Clark Boylan Date: Thu, 30 Apr 2020 16:23:51 -0700 Subject: [PATCH] Configure htcacheclean for zuul-web We are starting to use the apache2 mod_cache_disk functionality more now and during use the cache has grown into the 1.5GB range. The htcacheclean process is cleaning up every 2 hours which is how it is getting behind with its limit of 300MB. Reduce the interval to 15 minutes by supplying an /etc/default/apache-htcacheclean config. Note we cache status.json files which are only valid for a very short period of time. This likely explains the quick growth of the cache.
