Environment

• Liferay DXP 7.0

Resolution

• Generally, this kind of error is thrown when the start value in ServletResponseUtil is greater than the end (file length) in the code. There is an i/o operation being performed, specifically, a file is being sent which breaks down due to file range. The Code reference for the error:
  a) https://github.com/liferay/liferay-portal/blob/master/portal-kernel/src/com/liferay/portal/kernel/servlet/ServletResponseUtil.java, go to line 686.
