3.8 GB file gives issue - RangeError [ERR_OUT_OF_RANGE]: The value of "value" is out of range

[nitinrgoyal]

Using latest version of clamscan, I am getting the following error when I try to load a 3.8 GB file.

node-clam: Provided stream is readable. node-clam: Attempting to establish socket/TCP connection for "scanStream" node-clam: using local unix domain socket: /var/run/clamav/clamd.ctl internal/buffer.js:69 throw new ERR_OUT_OF_RANGE('value', range, value); ^

It seems like the buffer is filling up faster than it can be offloaded to the downstream target. Can you share the relevant part of your code?

No, it's writeInt32BE function failing in one of these places: https://github.com/kylefarris/clamscan/search?q=writeInt32BE

It cannot process value bigger than 4 bytes signed integer:
