Re: [twsocket] Fw: TWSocketServer maximum productivity
We'd like to find someone who is good in ics and could help to fix our problems with client\server for thousands connections (of course for some $$). Can you advise anyone ? Here is our test project: http://rapidshare.com/files/103140112/IcsBasedProject.zip.html Using ftManager program we are deploying NewClients with hundreds of ics clients in each and making heavy load. E.g. when just connecting 9000 clients - server makes Access violation at address 7C92BD02 inmodule 'ntdll.dll' . But under delphi debugger it is not handled. Occurs just after some minutes of usage, depending on client number (some minutes on 4000 and some seconds on 9000). Also, it depends on PC number, it's difficult to catch on 2 PCs (2500+ clients on each ) and easy on 30 (200-300 clients on each). We suppose, maybe it's (server) not correctly implemented and ics professional will easilly see some bugs. Thanks.

Re: [twsocket] Fw: TWSocketServer maximum productivity
Hello Alexander, I had this problem sometime ago, it was the very same message and occurs when client connects.. Unfortunally we didn´t found the fix for it because we couldn´t reproduce this error easily with our app. I suggest you to use Eurekalog, this is an error catching library, so you could use the eurekalog trial library on your running application, when the error occurs it will log on what point is has failed, giving detailed debug information on it. And please if you find a fix tell me The strange is that this problem only occurs on Windows 2003, we have lots of WinXP installations that don´t have problems, on Windows 2003 we have the same problem Éric - Original Message - From: Alexander Makhanev [EMAIL PROTECTED] To: ICS support mailing twsocket@elists.org Sent: Friday, March 28, 2008 7:08 PM Subject: Re: [twsocket] Fw: TWSocketServer maximum productivity We'd like to find someone who is good in ics and could help to fix our problems with client\server for thousands connections (of course for some $$).
