APAR status

• Closed as program error.

Error description

• The primary symptom will be slower performance on reading data
  from the cloud, reads are being done as part of the VE backup
  process,
  so those slower reads are impacting the backup. The issue is
  probably more noticeable in the VE backup case. However, any
  read from the cloud is potentially impacted.
  The main thing to look for is many threads spending time in
  SdSignalSPContainerHandler, in stacks like this:

  If servermon data shows multiple threads in this
  SdSignalSPContainerHandler function, then the performance issue
  is probably related to this code.
