I have done a lot of testing on many different systems but still haven't
figured it out exactly when the problem occurs. I have found that on
windows 7 64 bit and 2008 64 bit with Perl 5.12 and apache 2.17 from
apachelounge the problem is NOT seen.
I was only able to reproduce the problem on windows 2003 and 2008 R1
server 32 bit. But even here it was very difficult to reproduce it in a
situation where Apache actually restarted.

I found that there where two occasions of the APR error.
One that gives the real line number where the problem occurred:
 'APR does not understand this error code at /path/module line xxx'
This does not course the Apache to restart. 

The other error is: 
'Apache2 IO flush: (620018) APR does not understand this error code at -e
line 0'.
This causes Apache to restart.

The first error is seen in the log of the virtual host that runs the
ModPerl script. The other error is seen in the main apache error log file.

Any Idea what 'at -e' means ?

I have not tried Steve's patch yet, will do that asap.

Will be continued ..
