No buffer space available

My squid proxy has been running fine for over a year and over the last few weeks it has been failing randomly.

I have been getting the following messages in the cache.log:
comm_openex socket failure: (105) No buffer space available
oldAccept  FD 18, [::] [ job2]: (105) No buffer space available

Sometimes a restart of the service fixes and sometimes I need to reboot.
Server is Windows 2019 running in AWS
Squid is v4.14 from Diladele installer

I have tried reducing TcpFinWait2Delay and TcpTimedWaitDelay.

Any ideas would be very helpful!
