 Currently what I've is:

 = Build perl and mod_perl using the system malloc

that should be any platform where perl defaults to using its own malloc,
that is, if:
% perl -V:usemymalloc
reports:
usemymalloc='y'

which is fine if:
% perl -V:bincompat5005
reports:
bincompat5005='undef';

but the default for 5.6.x is:
bincompat5005='define';

which can be turned off with:
% Configure -Ubincompat5005 ...

 * My server leaks memory on restart with DSO
 
 = don't use DSO

shouldn't happen with 5.6.1, at least it doesn't with my testing.

Well... With 
 # perl -v

This is perl, v5.6.1 built for sun4-solaris

# perl -V:usemymalloc
usemymalloc='n';
# perl -V:bincompat5005
bincompat5005='define';

on  # uname -a
SunOS netra 5.8 Generic_108528-09 sun4u sparc SUNW,UltraAX-i2

am I safe? Or what should I rebuild with what flags?

Seems like I'm suffering from dying children problem... My main apache
dies sometimes, bringing neraly everything (well, except
server-status) down.

Alex.

how did you build modperl?  if USE_APXS=1 you may have missed this
other warning:

Your Perl is uselargefiles enabled, but Apache is not, suggestions:
*) Rebuild mod_perl with Makefile.PL PERL_USELARGEFILES=0
*) Rebuild Apache with CFLAGS=-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
*) Rebuild Perl with Configure -Uuselargefiles
*) Let mod_perl build Apache (USE_DSO=1 instead of USE_APXS=1)

the first option is the easiest cure.
