New Comment:
I enable ZTS, because I use threads. I have one IO thread and more PHP
threads. As I said, it isn't pure thttpd and PHP. My web server has
quite nice architecture - I have queues, processors, queue overflow
control etc.
About configure parameters - I use the same compilation on another web
aplications and it is working well. Difference is that they don't use
socket streams. They use oci8 and ldap without any problems. As far I
know oracle ldap functions doesn't perform well and we use iplanet
libraries with success. No problems with that.
I can reduce config.nice by only few modules (ftp zlib gdbm gettext
xml). Others are needed by my app.
Anyway - don't you think that these STREAM_DEBUG messages are strange?

You should reduce the configure options to bare minimum,
try with this configure line:
# ./configure --with-thttpd=../thttpd --disable-all --enable-debug
Why do you enable the ZTS anyway?
Also, using --with-regex=system is not wise unless you
REALLY know what you're doing. And Oracle has it's own ldap functions,
it's known problem that those might conflict with other ldap libraries.
Just point the --with-ldap to the same as you do with --with-oci8.

PHP is taken from snaps.php.net : php4-STABLE-200307081130
'./configure' \
'--with-thttpd=../thttpd' \
'--enable-experimental-zts' \
'--with-tsrm-pthreads' \

'--with-mysql=/usr' \
'--with-oci8=/opt/oracle' \
'--with-ldap=/opt/iplanet' \

'--with-zlib' \
'--with-gdbm' \
'--with-gettext' \

I've patched thttpd and PHP so it worked fine together in ZTS. I
haven't touched streams. It worked until streams were introduced
(4.3?).
BTW are memory and fds freed if there is no msg in log like
"stream_free ...."
I think I won't be able to write short script which reproduct this
error because it isn't on each request :(.

Thanks for the detailed trace;
A short self-contained reproducing script would help a great deal here
also.
Also, it seems that you are running a thread-safe build; could you let
us know the configure line you used, and also the version of PHP (are
you really using the PHP_4_3 branch of cvs?).

The function called from PHP userspace was fclose.
I also found in log 1069 msg looks like:
stream_alloc: socket:0x43d64f08 persistent=(null)
and only 48 msg pairs like:
stream_free: socket:0x4849caf8[(null)] in_free=0 opts=00000003
stream_free: socket:0x4849caf8[(null)] preserve_handle=0 release_cast=1
remove_rsrc=1
I also got about 40 core dumps.
If you want more information please describe what kind of information
you want.
