           Summary: Some bugs on Win2000
           Product: Apache httpd-2.0
           Version: 2.0.54
          Platform: Other
        OS/Version: Windows 2000
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Platform
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: pash_ka@fonbet.info


Platform: ASUS AP1600R (2 Xeon 2.4Ghz, 2Gb RAM)
Software: Win2000, Apache 2.0.54, PHP 5.0.4, MySQL 4.1.10a, no 
firevals/antivirus
Average server load: 5-10 requests/sec

First, I've noticed 
---
[warn] (OS 64)The specified network name is no longer available.  : 
winnt_accept: Asynchronous AcceptEx failed
---
warnings and very unstable behaviour of Apache: sometimes request had been 
processed in 20 ms and oter times - more than 3000 ms (since i was running 
tests on local mashine network perfomance was not an option, and this strange 
random responce times was tested on plain html-page with no scripting).

The solution I've found in bug 21425:
---
Win32DisableAcceptEx
EnableMMAP Off
EnableSendfile Off 
---
solved both of tis problems but inroduced another one: 
---
FATAL:  erealloc():  Unable to allocate 98304 bytes
---
Errors like this one occured every 5-10 minutes and caused server restart.
The only solution I've found is decreasing ThreadsPerChild setting from 350 to 
170. Since doing this I have not seen this error.

I've also noticed another problem: restarting server with "apache -k restart" 
command and even stoping it with "net stop apache2" failed to close child 
process. And sometimes lines like
---
[crit] [Thu Apr 28 10:54:23 2005] file .\\server\\mpm\\winnt\\child.c, line 
1078, assertion "(rv >= 0) && (rv < threads_created)" failed
---
(bug 11997) ocured in error log.

I've commented out "EnableMMAP Off" and now everything works fine. Or I just 
hadn't seen the problem yet. :)
