It will stop Squid from using ICP which is a waste of time and resources
if you only have one parent and no siblings, and even more so if the
parent does not support ICP..

If Squid fails to establish a TCP connection to the parent then it will
consider it dead until it accepts TCP connections again.

You should only get this if
a) Your parent have problems accepting the load it is given
b) and you use never_direct, which forces Squid to always try to find a
suitable parent.

What you need to do then is to fix the problem with the parent cache.
There is not much Squid can do if it must go tru a parent and this
parent is failing to accept the requests.
