Cumulus Networks Product Bulletin 2016-01-26: Memory Leaks



Three memory leaks have been discovered in switchd:

  • The first affects all customers.
  • The second occurs when there are IP neighbors in the system.
  • The third occurs when one or more interfaces are operationally down, and if any routes or neighbors are learned on a down interface, they are kept as “dead” routes/neighbors in the kernel. When switchd syncs these dead routes/neighbors, the second leak occurs.


Cumulus Linux 2.5.4 - 2.5.5


These issues have been fixed in Cumulus Linux 2.5.6, so it is strongly recommended you upgrade to Cumulus Linux 2.5.6.
