osysmond.bin socket leak causing RAC node hang and ACFS issues (Doc ID 1526421.1)

Last updated on JANUARY 24, 2020

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.2 and later
Information in this document applies to any platform.

Symptoms

One of the RAC nodes could be hung and unavailable from SSH. The node can only be reached from the console.

On the other nodes, the "df -k" command may be hung, and ACFS mount points may disappear.

A reboot of the problem nodes can temporarily resolve the issue and resume the ACFS mount points.

Found the many errors in the OS system log of the hanging node.
