We have tested with a fsimage with about 140M files/directories. The peak heap usage when processing this image in pre-protobuf (i.e. pre-2.4.0) format was about 350MB. After converting the image to the protobuf format on 2.4.0, OIV would OOM even with 80GB of heap (max new size was 1GB). It should be possible to process any image with the default heap size of 1.5GB. > Another issue is the complete change of format/content in OIV's XML output. I also noticed that the secret manager section has no tokens while there were unexpired tokens in the original image (pre-2.4.0). I did not check whether they were also missing in the new pb fsimage. -- This message was sent by Atlassian JIRA (v6.2#6252)
