apache
>Release:        1.3a1
>Environment:
Windows NT 4.0 SP3, *Dual* Pentium Pro, Apache 1.3a1, VC++ 5.0
>Description:
When we run a performance driver requesting a simple cgi page against Apache 1.3a1 / NT,  it runs fine when only one requestor is running.  If we run two copies of the requestor, the apache server will hang (for all requests, even non-cgi) within a minute.  Once hung, even non-cgi requests no longer get *any* response after a connection is established.   The cpu(s) are relatively idle.

Requests that are non-cgi do not exhibit this problem.  The same CGI program under Netscape Fastrack exhibits no problem with any reasonable number of requestors.
>How-To-Repeat:

>Fix:
Not yet, we will investigate this further.  We are just posting this to ensure you receive feedback on the alpha release.  Overall, we are very impressed so far and will likely recommend Apache to our customers
