Yes, since upgrading to NetBSD 6.0.

I am running aapche22.

I am not sure when I am getting the core dumps. I can say this, if I 
delete my apache error_log and then restart it, then within minutes I have 
hundreds of segmentation faults.

Maybe I don't understand what I am looking at, but I only see one 
semaphores:

ipcs -s
IPC status from <running system> as of Sun Jan  6 11:31:39 2013

Semaphores:
T        ID     KEY        MODE       OWNER    GROUP
s    131072          0 --rw-------  webuser webgroup

Would this be enough to overwhelm sokva?

Also, would this remove them:
"for i in $(ipcs -s | grep www | awk '{print $2}'); do ipcrm sem $i; 
done"

And will it effect pure_ftpd?

Thanks,
Al
