Hi

I am having the same problem  as bug #11676 on:
Linux  2.2.12-20
Apache/1.3.20 
PHP/4.0.6
(Also tried Apache 1.3.19 with Php 4.05)

./configure  --with-apache=../apache_1.3.20 --enable-track-vars --with-oracle=/u01/app/oracle/product/8.1.5 --with-oci8=/u01/app/oracle/product/8.1.5 --with-mcr
ypt=yes  --with-gd=/usr/local --enable-apc --with-mhash  --enable-sigchild

(tried with and without enable-sigchild)

The problem does not seem to relate to a specific script and the apache status page shows different last scripts.

Another server running the same scripts and version, but on kernel 2.2.14 does not seem to have the same problem.

Sometimes when it goes into the race condition there is an oracle zombie process attached to it.

Regards
Anthony

One more thing, I think it is related to apache cleaning up unused processes to reduce to MaxSpareServers because it only seems to happen to processes near the end of the apache status list. I cant say for 100% certain, but it looks like doing a graceful restart on apache can also induce the error, but only sometimes.

This may be a bug in PHP, but also bug in your kernel/glibc.
Could you upgrade kernel and your PHP to 4.1.0 and report the result.

No feedback. Closing.
