Excessive disk usage of /var/lib/qpidd on Satellite6 managing over 2000 Content Hosts with katello-agent

Issue

• Running katello-agent (goferd) on more than 2000 Content Hosts and some larger patching activity via the agent happened recently. Since that time, disk usage of /var/lib/qpidd continuously grows or skipped few times extraordinary. No service restart happened (cf. [Satellite6] /var/lib/qpidd disk usage grows over time, esp. after qpidd restart)
