[notice] caught SIGTERM, shutting down ?

[Chris M.]

Now I've been searching the net endlessly looking for a solution as to why apache is shutting down and not coming back up at all unless I restart it.
I looked at http://kb.odin.com/en/132 and http://kb.odin.com/en/4470 both saying this is normal and to ignore it but my site won't come back up from a "browser request".

I'm running on Debian 4 etch with Plesk 9.0.1, I did apt-get update, and apt-get upgrade just now and nothing new.
This is my "/var/log/apache2/error.log"

The "[notice] child pid ##### exit signal Segmentation fault (11)" never stops now, it's always a different number and keeps going.

I have the same problem, at night (not every night) at 1:12 apache shuts down "[notice] caught SIGTERM, shutting down"
and not coming back up ether.
I'm running on Debian 4 etch with Plesk 9.0.1 too

Resolved

Since no one replied with an answer, I resolved it somehow.
This started about a day after I enabled support to SSL on my domain.
So I disabled SSL support and apache kept shutting down, so then I made a thread here.
My friend tweaked the apache configs a bit and I rebooted the server, now apache never shuts down.

But if this doesn't work for you Fred, try an auto restart apache script similar to this one.

Good luck

Hello Cris,

Thanks for replay, i changed the apache config also

MaxClients was set to 100, i changed to 50 for now.
Found it on this forum, let's hope it works.

Hello Cris and Fred

I met the same problem in apache2, can you give me more detail about the apache configure file?
I use the following module:
<IfModule mpm_prefork_module>
ServerLimit 5000
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 3000
MaxRequestsPerChild 10000
</IfModule>

And for SSL, I must use it for project requirement.
Thanks very much!
My mail address is: [email protected]
Best Regards!

I read somewhere that you should have a seprate IP address in order to implment SSL. i.e You can not share it with other domains. Perhaps this explains the name issue?

http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html#vhosts

Also, pleak over writes the files :

/zz010_psa_httpd.conf and zzz_horde_vhost.conf so I am no sure how you go about setting the correct settings in the vhost conf file if indeed this is what is expected?

Tried to search for knowledge base and could n't find anything relevant there. Would like to know what your firend has done differnet as I am sure there are plenty of plesk users who would also like to know.
