Environment

Release : 20.3

Component : UIM - APMGTW

Cause

A cause of this could be that the cache files (mapdb) are corrupted within the apm_bridge folder.

This issue can occur due to some invalid data (NULL values) fetched from the UIMAPI request. This may cause issues w.r.t serialization/deserialization of the values within the mapdb.

 

 

Resolution

  1. Deactivate the apm_bridge probe.
  2. Rename/delete cache & store folder within apm_bridge folder. Cache folder will have a large number of 1 KB files in most deployments so deleting will take a very long time, so         
      renaming the folder would work.
  3. Activate the probe.
