Thanks @dudanogueira I have everything resolved. I used this thread to get the database files resolved

Attachments take ages to upload and view

opened 04:00AM - 24 Jan 22 UTC

We have an issue after upgrading our Rocket.Chat install to the latests, server …/ client and MongoDB (see versions below) After upgrading, first to wiredTiger, then to version 4.2 / 4.4 then 5.0 all attachments added to chats i.e. images / audio / video etc take an inordinate amount of time. Also clicking on these attachments also take an inordinate amount of time to show or start playing. By inordinate I mean 3 - 5 minutes to show images or upload new attachments as oppose to just a few seconds previously. None of our attachments are particularly large and affect ALL existing attachments (viewing) and new attachments (upload and or view) ### The stack trace I get the following stack traces in the Rocket.Chat logs which seems to indicate a missing parameter OR missing indexes. Any ideas how to fix this will be appreciated.. ufs: cannot read file "mC3nrWQ3cY7ifoJwz" (Executor error during find command :: caused by :: Sort exceeded memory limit of 104857600 bytes, but did not opt in to external sorting.)
