There is no 2.41 nor 2.43. I guess you talk about 2.4.1 and 2.4.3. My
statements are for those releases.

There is no change between those two versions regarding that. The only
changes are a fix for URL Auth as well as a way how brokenness of
Microsoft's filesystem is worked around.

There is no such setting. The maximum length of a single Vorbis Comment
Tag is about 2^32-1 Byte (4GiB).
I highly suspect that this is something in the source client not sending
data correctly. Feel free to provide the URL of your stream so I we can
have a look at it.
Have a nice day!
With best regards,
 Likely there is a much smaller limit as you may run out of memory
 A maximum of 2^32-1 headers can be stored. The total vorbis comment
block would be 16 EiB large.
