Hi,
We have HMail Server 4.2.2 running on our web server (Windows server 2003 web edition) and we are using Winclam (V 0.90.2.1) to scan all emails via Hmail.
We have had this set up for a couple of years but recently we have found that Clamwin is using 100% of processor power so the server was impossible to log in to and use. Last week we upgraded the server to a new one (3Ghz pentium dual core processors.) Same operating system. We installed Hmail 4.2.2 and re-installed the latest version of Clamwin and exactly the same problem has occurred. When we turn on Clamwin through Hmail Server it starts using 100% of both the web servers processors!!
We tried to install HMail 4.4 to see if this fixed the problem but this had compatibility issues so we've had to revert back to 4.2.2.

Does anyone know what could be causing this problem??
At the moment I have had to turn off Clamwin so the server can do it's job.

Some changes were made with the current version to address a similar problem in Outlook, but that is probably all they are going to do. The current program architecture is memory intensive. Version 1.0 will have different architecture and will run much more efficiently when it is released. There is no set release date.

Regards,

It's already fixed in clamav 0.91. When next version of clamwin will use this version the problem shoul be fixed.

Thanks for the information.
Seems like we'll have to sit tight and rely on just our anti virus on our PC's for the time being!
Not good but I hope Winclam bring out a fix soon.
