Apache v2 stops accepting connections randomly (win32)

I have this problem on two different machines:
  Apache randomly will stop accepting connections.  I am unable to telnet to port 80, or use a web browser to conenct to the machines.  Even on the machine locally I am unable to connect either way.

  The service will run for hours fine, then suddenly it stops accepting connections, and will start accepting them about 2-5 minutes later.

  The apache monitor in the task bar shows green, and the service status is running.

  In task manager, the apache processes are there like I normally see, and they are not using any excessive time or memory.   Usually little or no time actually.

  This has been happing for a long time, and I have not been able to track it down so far...

  No obvious errors in the apache error log.

  Nothing in the Windows event logs...

   Running latest apache v2 (.50).

   Two different computers have this problem.    One is Windows 2000 Pro, other is Windows XP Pro.
 
   The only common software between the two is Apache (though the 2000 pro machine is running an older version), and both are running WSFTP Server (latest version).

   I have tried turning off the WSFTP Server service on one of them, and that didnt fix it.

   Any things I can check, ideas, etc. ??

Thanks!

This could be a problem with the number of people connecting if you check you apache config you will see what the limit
is for the number of people viewing the site. you may want to increase the number

Good thought.   I did check that already, and upped it.    Neither server is very active generally, so I dont THINK that is the problem, but is there a way to tell if apache has been shutting down due to that, maybe because of a hacker?

if you check apaches error log it sometimes will tell you why it has shutdown
you also may could be being DdoSed (Distructible Dental of service) by someone like a cracker

The only things I see in the error log are messages about "File does not exist" -- looks like people hitting bad URLs...
 
 Also some warnings for "(OS 64) The specified network name is no longer available. : winnt_accept: Asyncronous AcceptEx failed."  here and there, but not always when I have the connection problem.

 Any other suggestions to look at?   Ways to see more log data?  Maybe use performance monitor (I need guidance on that though)?

Thanks.

Another thing I have running on this machine (but not on the other) - MySQL - it seems to loose connectivity too fairly often.
I used to have MySQL running on the other machine, but I stopped the service quite a while ago.

I would suggest that you upgrade your Apache version to version 2 that may help solve this issue
also were did you get the apache server from?

Thanks, but it is not a 64 bit machine.
One machine is a 400mhz Intel, and the other is a 300mhz Intel - both 32bit processors....
??   Or do you mean something else?

I have not tried Apache v1, and I think there was a feature in v2 that I needed which is why I am running v2 - I think maybe SSI, but not positive...

Ok, update:

I was able to fix my connectivity issues with apache by downgrading to version 1 from version 2 of apache, but I do not LIKE this solution.

For now it is ok, but isnt the future of apache in version 2 and above?

It seems like I should be able to run version 2 without this problem right?
