Topic: libapr-1.dll error on Apache 2.2.15 serving Subversion

[zshamim]

I installed Apache 2.2.15 to serve Subversion 1.6.6.
This set up has been working fine on Physical box till the time we switched to Virtual box.
Now with same set up we keep getting error
"This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
[Mon Oct 07 02:27:30 2013] [notice] Parent: child process exited with status 255 -- Restarting."

In windows event log we get the message "Faulting application name: httpd.exe, version: 2.2.15.0, time stamp: 0x4b8fed95
Faulting module name: libapr-1.dll, version: 1.4.2.0, time stamp: 0x4b8fed79
Exception code: 0x40000015"

In addition to default modules we are using
mod_dav_svn.so
mod_auth_sspi.so
mod_authz_svn.so

for authentication.

we are using Windows 2008 with 16 GB RAM.
Tried so many tweaks to httpd.conf
Current directives are
ThreadsPerChild 600
MaxRequestsPerChild 6000
ThreadStackSize 8242880

Error crops up only where there is major checkout from Subversion else Apache is working complete fine.
Anypointer would be a great help.

You may try the last version of mod subversion to see if that fixes your error.
