Andy,
I found that this causes big spikes and valleys because Declude will
batch process E-mails. i.e. it moves in x number of message pairs to
work and doesn't keep moving in newer files while it waits for that
batch to finish processing fully, and your CPU goes to zero, then it
resets the Winsock and moves another batch into Work and the CPU spikes
back up to 100% (if you have a moderate amount of volume.
I would only use this if you are having an issue. I too turned it on
just to be safe, but it has some bad effects. I am not aware of any
Winsock issues since upgrading to 4.x.

Thanks Dave.
So:
a) Does the scenario that I described (which was not specific to
IMAIL or Declude but also effected other TCP/IP applications on that
machine) still "fit the bill"?
b) What if I were to turn on WinSockCleanUp just to be safe?
What risk do I take? What is the negative impact? What will "resetting
the winsock" cause with respect to other TCP/IP applications?
Performance impact? Stability impact? (After all, if there IS no
impact, why would it not be ON by default)?
c) Imail Bug: Has Ipswitch acknowledged that bug, e.g., they are
fixing it? Or is that something that we still need to take up with
them? That option is quite old and IMail has seen several new versions
since then... So I wonder!

Some installs of IMail had an issue where there winsock would cause
problems for network functionality, this was a bug in Imail, it seemed
by stopping smtp32 service of Imail resolved the issue. Declude uses
the winsockcleanup to reset the winsock to deal with this.
winsockcleanup kicks in when the \proc directory is empty or reaches 0
files Decludeproc will reset the winsock.

Hi,
Does anyone have any comment on the attached email (possibly even
Declude personnel)? I checked the mailing list archive -- and it
seems to imply as if the WinsockCleanup is specific to DNS problems
and results in queues filling up. In my example, Imail and Declude
didn't seem to be filling up queues. The couldn't because TCP/IP would
not let any inbound connections go through...

Hi,
What are the symptoms related to Winsock Cleanup?
After running fine for 2 months or so (except for occasional reboots
for Hotfixes), the mail server stopped working on the TCP/IP level. It
didn't respond to Ping from the outside. You could log into the
console and Ping to itself.
There was also some notice about a Browser Election during the outage
-- so it seems as if there was still communication on the Ethernet
layer (such as LAN segment broadcasts). A reboot resolved the issue.
Does this sound like the situation that this option is intended to fix:
*#WINSOCKCLEANUP some customers had issues related to their network
stack causing loss of functionality for basic *
*#network operations.The default for this directive is OFF*
* *
*#WINSOCKCLEANUP OFF*
Is it consistent with this problem, that the server might have worked
fine for a few months and had been rebooted just a few days prior --
and to suddenly display this behavior?
What's the impact if that is set to "ON" unnecessarily?
Best Regards,
Andy
