Category:	MySQL Server: Replication	Severity:	S2 (Serious)
Version:	5.7.19	OS:	Linux
Assigned to:	MySQL Verification Team	CPU Architecture:	x86

File:	Maximum allowed size is 50MB.
Description:
Privacy:

If the data you need to attach is more than 50MB, you should create a compressed archive of the data, split it to 50MB chunks, and upload each of them as a separate attachment.

To split a large file:

On *nix platforms use the split command e.g. split -b 50MB <my_large_archive> <my_split_archive_prefix>
On windows use WinZip or a similar utility to split the large file

I debugged the steps with gdb until we get into the problem.

Attachment: gdb debug (application/octet-stream, text), 12.41 KiB.

I am attaching another file with some extra debug in gdb showing the mentioned. Uploading again as public.

Attachment: gdb debug 2.txt (text/plain), 40.39 KiB.
