Hi There,

Running:

Apache 1.3.12 PHP4.0.0 OpenSSL 0.9.4 MOD_SSL (latest) ..

Everything works perfectly, running away, serving our site and working quite quickly. Users notice no errors at all, and service quite good... but..

If you type "dmesg" under FreeBSD, you get a large list of records like this:

pid 609 (httpd), uid 1013: exited on signal 11

Basically, httpd is seg faulting all the time. Now, it seems to me that this is ONLY happening when an httpd process closes itself down. People can connect and view their pages and whatever ..httpd processes are spawned and everything works nicely .. right up until the point that the httpd process closes, at which point it seg faults. 

I think that someone else has reported a similair problem under FreeBSD-Current (5.0).

I never had this problem under FreeBSD 3.4-STABLE, so I assume that it might be a 5.0/4.0 specific problem, as I believe that 4.0 and 5.0 are more alike then 3.4 and 4.0 are. 

This is not a terribly critical bug.. as I said, users don't seem to notice a problem, but it would be nice to keep my console from displaying segfault messages all day.


Thanks,

Dylan Neild

One other thing .. the ONLY other difference between the old 
FreeBSD 3.4-STABLE machine (which, as I said, never exhibited this
problem) and the new FreeBSD 4.0-STABLE machine is that the
new machine is SMP. The old machine:

FreeBSD 3.4-STABLE
Pentium III-500
1GB PC100 Memory
10GB UltraATA 66 Disk

The new machine:

FreeBSD 4.0-STABLE
Dual Pentium II-450's
ASUS P2B-DS Motherboard
1GB PC100 Memory
1 x 9GB Ultra2 SCSI Boot Disk
2 x 9GB Ultra2 SCSI Data Drive (Where APACHE/PHP/MYSQL) resides. This disk is a RAID0 striped disk.

I am willing to provide any other assitance I can to help solve this problem, so feel free 
to send me an e-mail. 

Later,

Dylan

Hi Again ..

CVsupped to the latest 4.0-STABLE this morning, 
upgraded my mod_ssl to the 2.6.5 maintenance 
release, and upgraded to 3.23.21-beta of MySQL.

I've been running for over an hour now with none of the 
sigal 11 exits from Apache/PHP.

Well, so I guess we can close it then, since it works. Please reopen if the problem resurfaces.
