i dont have shell access [not that i am aware of]
what should the host do?

You definitely need to do something about it. 900MB a day is too much. Your host, if they're the least bit competent, should be able to figure out which binary program is going belly up (most likely, PHP or MySQL), and then what it was doing at the time. If the program is very down-level, they should get up-to-date. Otherwise, they'll need to work with the program's developers to see what's causing the program to die (what scripts or input are the problem).

well, i contacted my host letting them know some of the information i found here.

the host repsonds thus

Quote from: TechSupportThis problem is created by software version you are using. This is a beta version and beta always creates nuisance.

Please revert back to most stable version or the tech may feel that you are misusing the resources. This amy cause more trouble.

Please ask the developer to provide a fix or solution to this. We are not going to modify anything in php or apache just for the sake of this script.

the funny thing about it is i am not using 2.0beta version i am running 1.1.5

even funnier is the host seems to have crashed  the server. i cannot get access  to any of their sites. http://damnx.us or anything that i had hosted with them

luckily i had a working back ups and recent copies of the database.

i'll have to see how things unfold.

Wow. Some hosts are just very incompetent... A script isn't the problem because it can't do anything that the code running it won't allow. Read response 25 on this topic for a bit of a long discussion on why the script isn't really the problem.

All I can do from here is to wish you luck.

i updated my support ticket informing the host that i was not using a beta version of smf. i got the following reply

Quote from: [email]TechSupport@damnx.us[/email]Wworking on your issue caused server down for last 12 hours and many refunds are raised causing heavy financial loss just to resolve your issue.

Tech is still working but cannot assure solution as server and all cl;ients are more important

Wow...

I think they are just trying to use use you as a scapegoat. Seriously, running gdb for a backtrace shouldn't cause an outage.

I don't want to sound mean or anything, but I encourage you to find a better host that won't offer up such poor excuses and blame you for things.

i have been looking for a host this morning, to be honest i am fed up with hosts. i dont know what to do for the best. the one i am with has been okay except for this problem. i have good uptime and the server is never slow. i hear horror stories about the larger hosting companies. right now i am on a free host as a back up until i can be sure it is safe to go back to my paid host.

You can always ask over at our Hosts, Hosting and Commercial Services board. I also recommend doing som research over at Web Hosting Talk.

Every host has problems, but some are better than others.

My core dumps all went away after I disabled hostname lookup.

Mine persist.  I guess i'll have to give it a go at figuring out why they're being generated

I got a load of them for the first time a few days ago when the server threw a wobble. Part of my host's response:

"You can delete the core dumps from your forum folder. These files are created whenever segmentation fault occurs. I've disabled core file generation when programs crash - they're rarely useful in our environment and will save everybody hassle."

Sorted.

MrPhil

Wow, talk about putting a Band-Aid over a gaping wound! Your host should be doing something about finding out why there are so many segfaults, rather than just turning off core file generation and pretending there's nothing wrong. I can only hope that they've gotten enough dumps to look at and are busy working on a fix, and that the no-core policy is just temporary.

青山 素子

Agreed. Segmentation faults will occur occasionally, but multiple ones in a day is way too much and that needs to be looked at.

ellion, did you find what causes the core files?

ellion

hi,

i never found the cause of them, my host eventually came to realise that it was the server that was bugging not smf. he moved my account to another server.

which has been absolutely fine. no problems at all.

during the process of migration from my buggy server to the new server there was a couple of days where i had the forum on the buggy server not being used but still accessible via ftp.

the core dumps where still being created in the public directory of the old server despite the forum not being used and the public directory not being accessed. the core dumps were being created at the same rate. i think this confirmed for me that this was a server bug not a smf bug.
