Oh dear! Good find. I am on vacation until mid next week, I will fix that when I get back. For now, you may need to disable indexing with :

"sessionrecording": {
  "index" : false
}

[petervanv]

i already did that so, happy vacation

Published MeshCentral v0.4.9-q with a fix for this. The problem only happened on single CPU servers and would happen on all recordings. Let me know if it works for you.

Hey ylian,

Unfortunately not, this error im getting now, with the recording and index on:
-------- 2020-3-3 11:29:52 ---- 0.4.9-r --------

internal/buffer.js:72
throw new ERR_OUT_OF_RANGE(type || 'offset',
^

RangeError [ERR_OUT_OF_RANGE]: The value of "byteLength" is out of range. It must be >= 1 and <= 6. Received 8
