[squid-users] Need help with Squid on Windows

Hello Jason, Amos, all,
Possibly the issue can be related to Squid being compiled with Cygwin https://cygwin.com/ml/cygwin/2012-03/msg00302.html, I'm not sure whether this issue with standard output has been fixed in the current Cygwin.
One of the workarounds that could possibly work is to install Cygwin and build squid yourself as described here: http://docs.diladele.com/tutorials/build_squid_windows/index.html, this should start helpers from Cygwin terminal instead of cmd.
Please take a look at Web Safety - our ICAP based web filter server for Squid proxy at http://www.diladele.com.

You usually need to enable debugging in the helper itself to get that.
Squid only knows that the helper died on startup.

FWIW: Nothing has changed inside Squid for helpers between those two releases.

Maybe something left over from this previous aborted Squid instance and its helpers that kills the next one to start?

Note that it is only the 6th helper that dies. The first 5 seem to be okay at this point.
Maybe something they share which has a limited connection count?
