java.lang.IllegalArgumentException: Mutation of X bytes is too large for the maxiumum size of Y

[George Sigletos]

Hello,

I have been frequently receiving those warnings:

java.lang.IllegalArgumentException: Mutation of 35141120 bytes is too large
for the maxiumum size of 33554432

Sometimes I can trigger them myself by trying to add the contents of  a
text document that is less than 1 MB.

Initially I did increase the "commitlog_segment_size_in_mb" from 32 to 64.
Thinking to further increase it to 96.

But would that be a solution to the problem? What could be possibly causing
this?

Thank you,
George
