How to fix SVCHOST.EXE REGSVR32.EXE Application Error Memory Could not be written / read

I have been seeing a window pop up with this error message every time I start my system "Generic Host Process: Application error - [ Memory Address ] referenced memory at [ Memory Address ]. The memory could not be 'written.'" even after I removed a trojan W32.Spybot.ATEW. Regular scans by Symantec AV and also Trojan Remover didn't report any malware. I searched for SVCHOST.EXE and I found this prefetch in %SystemRoot%\Prefetch

SVCHOST.EXE-3530F672.pf

I deleted it and rebooted my system. The error has disappeared.

For all kind of memory related problems for any of windows OS applications like svchost.exe, regsvr32.exe, etc., you can follow this article to resolve it. Say, if you have cleaned your system of Trojans and Viruses, you must also check the prefetch folder under WINDOWS directory for the file names that have similar file names as the application name displayed in error window. If you find any, its recommended to delete these files and reboot the system.

Installing and Configuring apache flood on CentOS

I have often found that installing flood on 64 bit machine with CentOS fails.

you can follow these simple steps to install flood on your system

Download flood from

svn co http://svn.apache.org/repos/asf/httpd/flood/trunk flood

or

Browse to http://www.apache.org/dyn/closer.cgi/httpd/flood/ and download from a mirror

If you want to install on remote machine you can also

wget http://apache.mirror.facebook.net//httpd/flood/flood-0.4.tar.gz

untar the compressed file where it is downloaded on your system by issuing the following command

[root@myserver] tar zxf flood-0.4.tar.gz

dowload apr-1, and apr-1-util from http://apr.apache.org/download.cgi

wget http://apache.opensourceresources.org/apr/apr-1.3.5.tar.gz
wget http://apache.opensourceresources.org/apr/apr-util-1.3.7.tar.gz

untar both apr files as it was done for flood

[root@myserver] cd apr-1.3.5
[root@myserver] ./configure
[root@myserver] ./make
[root@myserver] ./make install

and now for apr-1-util

[root@myserver] cd ../apr-util-1.3.7
[root@myserver] ./configure
[root@myserver] ./make
[root@myserver] ./make install

after installing both apr and apr-util flood can be compiled and installed; flood is built on top of these utilities.

[root@myserver] cd ../flood-0.4
[root@myserver] ./configure --with-apr=/usr/local/src/apr-1.3.5/apr-1-config --with-apr-util=/usr/local/src/apr-util-1.3.7/apu-1-config
[root@myserver] ./make
[root@myserver] ./make install

Optionally you may have to get a shell script from http://linux.derkeiler.com/Newsgroups/linux.redhat/2005-03/0373.html if at the time of configuring you get errors like x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized


Happy Flooding!!!
