3694999 - SAP HANA Recovery fails with OOM despite sufficient memory due to backup catalog overload and corrupted log backups

During RECOVERY RECOVER DATA or point-in-time recovery, SAP HANA database recovery fails with Out-of-Memory (OOM) errors or becomes extremely slow, although sufficient physical memory is available and the system size has already been increased.

Typical symptoms include:

• Recovery terminates with
  RECOVERY RECOVER DATA finished with error: [448] recovery could not be completed

• Errors indicating corrupted log backups, for example:

  • [110059] The backup … is corrupt

  • [3040118] Invalid buffer header found in log segment

• Backint errors such as:

  • [110507] Backint exited with exit code 87 instead of 0

• Restore progress is extremely slow during log replay

• OOM dumps generated during recovery

• Messages such as:
  Error in local merge: not enough merge tokens for delta merge or optimize compression

Increasing VM or host memory does not resolve the issue.
