apachectl gracefult causes Signal 11 crash after 6.3 to 7.0 upgrade

Wed Jun 4 16:08:11 UTC 2008

Hi all,

I think the subject is descriptive enough, but let me to explain again:

Some days ago I've upgraded from 6.3 to 7.0. The only problem is when I
do 'apachectl graceful' I get aways a Signal 11 fails. The
/var/log/messages shows:

[...] kernel: pid 90500 (httpd), uid 0: exited on signal 11 (core dumped)

I've done some STFG and I found this interesting resource:
http://www.zend.com/support/knowledgebase.php?kbid=173&view_only=1

But, unfortunately, it seems doesn't work.

In another 6.3 boxes I've these values:

kern.ipc.semmni: 10
kern.ipc.shmseg: 128
kern.ipc.shmmni: 192
kern.ipc.shmmin: 1
kern.ipc.shmmax: 33554432

I the 7.0 box the values are exactly _THE SAME_ and I get the error.

Several tests I've done:

* increase the shared memory using sysctl(8) on kern.ipc.shm*
parameters. No successs.

* reorder the PHP extensions as I've in 6.3 boxes. No success.

Moreover, after upgrade the system (kernel+userland) I recompiled all
the installed ports as official documentation advices (portupgrade -fa)

Some useful info:
