These events seem to increase, but only one process gets to the limit of
3x00 handles and then the other processes seem to hang ...

Hi,
yes this is Dildale's last available package. Output of squid -v is as
follows:

The helper negotiate_kerberos_auth.exe doesn't produce a Version output.

Hi,
i'm uncertain, wether this mailing list is the correct one to ask,
but i have the disputable honor to make a squid running on a Windows
Server (if possible). Whilst squid.exe seems to run fine, i
constantly run into an unresponsive system, when i enable Kerberos
authentication via auth_param and the negotiate_kerberos_auth.exe
helper.
For a while authentication works fine, but all at the sudden the
system hangs at 100% CPU usage. My Observation is that one of the
negotiate_kerberos_auth.exe processes has a constantly increasing
number of handles (Files and events). If i understand the
Sysinternals handle tool correctly, most handles are event corrolated.
The setting:
Windows 2012 R2 AD Controllers with Windows 2008R2 Domain Level. A
Windows Server 2016 running Squid 3.5 for Windows.
Is Squid the package built by Diladele or a custom build?
Which exact version number is it? (output of "squid -v" please)
Amos
