In Ubuntu, the attached patch was applied to achieve the following:

[Impact]

 * Whenever a user uses "crm node standby" the code can make lrmd still
   try to monitor resource put into stand-by and cause error messages.

[Test Case]

 * To use "crm node standby" and check lrmd does not stop monitoring
   not set to stand-by.

[Regression Potential]

 * users already tested and are using in production.
 * based on upstream fixes for lrmd monitoring.
 * potential race conditions (based on upstream history).

[Changelog]

  * Fix: services: Do not allow duplicate recurring op entries - 1/3 (LP: #1353473)
  * High: lrmd: Merge duplicate recurring monitor operations - 2/3 (LP: #1353473)
  * Fix: lrmd: Cancel recurring operations before stop action is executed - 3/3 (LP: #1353473)

[Fix]

I wasn't able to reproduce this error so far but the fix seems a straightforward cherry-picking from upstream patch set fix:

48f90f6 Fix: services: Do not allow duplicate recurring op entries
c29ab27 High: lrmd: Merge duplicate recurring monitor operations
348bb51 Fix: lrmd: Cancel recurring operations before stop action is executed

Thanks for considering the patch.
