cups-browsed memory consumption in RHEL 7.7 and RHEL 8 increases monotonically

Issue

• CUPS is able to keep pace with printing, until the server runs out of memory due to cups-browsed consuming it all.
• cups-browsed memory usage increases monotonically during use
• Memory consumption of the cups-browsed process on the client is increasing gradually and consuming most of the memory resources in the host.

• The kernel is reporting an out-of-memory (OOM) condition. The following entries are found in the system log:

  Feb 17 13:57:44 ny17u4118 kernel: Out of memory: Kill process 2128 (cups-browsed) score 583 or sacrifice child
  Feb 17 13:57:44 ny17u4118 kernel: Killed process 2128 (cups-browsed), UID 0, total-vm:64695240kB, anon-rss:51581276kB, file-rss:0kB, shmem-rss:0kB
  

  After this, print queues become disabled.
