Can anyone tell me how to delete files that are noted as:
upload_2014-2-3_7-48-12.png
I have 1131 MB of mystery files that are filling and exceeding my quota.
My site is whstech2.x10.mx

Please don't create tons of topics -- it's considered spam. I've been looking into the issue, but I'm waiting on more info from an administrator.

Also--May I ask why this is an issue? You don't have a disk quota... you're unmetered.

I apologize as that was not my intent. I have never encountered this before with the site and it is used on a daily basis with my students. It is a a major tool they use every day.
When more than 3 people log into the system it hangs up. I thought it was a resource issue due to space needed but apparently not. What would be causing the bottleneck?
Is it a bandwidth issue on your end?

I'm not part of the staff, but I have experience with this issue. Sometimes it's caused by faulty/outdated scripts being run on the server, which tends to happen a lot on free hosting with its multitudes of (no offense to anyone, just being realistic) frequently novice or inexperienced users. The resulting errors are all logged and the logfiles themselves, something intended to help diagnose problems, cause the problem. Error logs in excess of a gigabyte have been found, like electronic cysts or tumors on servers.

Sometimes it's caused by, or compounded by, what is known as memory leakage. This is when processes run that can't be terminated, like turning on a tv, changing channels, and the other channel not going away, or something. These processes sometimes loop infinitely, and can only be stopped by restarting the server, whereupon they begin again as soon as someone visits the site with the faulty scripts. This in turn often bloats the error logs, making it even worse.

The only solution, aside from occasional rebooting and deletion of morbidly obese logfiles is to use scripts and applications on your site that are, to use building parlance, up to code.

Sorry I can't do anything to fix your problem, but I hope the information can be of some use somehow.

phoebex2:
Thanks. I have gone through my site which is only running Moodle and can't see any nasty big logs or error files. On my disk size report it does show over a gig of files in an area on server I can't get to and I can't understand how they got there either!. I think my hands are tied until I get site admins to look into it.

If it's outside your account, you probably don't really need to worry about it affecting your account's performance or anything. It's good to point it out when you get a message about something like this, so at least the admins can fix it if they think it's going to cause problems, but like leafypiggy said, you probably don't need to worry about it too much personally.

If you're unmetered, it won't juke you out of an account to have something outside your area of access doing something funky, but it's still responsible of you to mention it so they can fix it if they see fit.

In the meantime, if you're experiencing any anxiety over whether it's you causing it or not, Google the scripts you're running for anything involving memory leaks or excessive errors and see what you can find out.

It's what I'd do, anyway, if only to make myself feel better about whatever part I might have in it.

Moodle isn't exactly a lightweight script (it does a lot) and you only have so much memory (that's RAM, not disk space) and processor time at your disposal (64MB and 300 cpu-seconds per hour respectively). Not to mention that you are sharing a server with thousands of other accounts. Don't expect it to be snappy on Free Hosting with multiple concurrent users.

Honestly, you may need more hardware resources than you would have available on a Free Hosting server to do what you want to do (depending on what you want to do, of course). Stepping up to Illuminated will double the available memory and put you on a much less-crowded server at a very reasonable cost, and that may give you enough headroom to make things work smoothly. Premium would give you plenty of room, but I understand that the budget may not be there, and I'm not trying to sell you anything (I wouldn't get anything from it in any case). But it is a fact that Free Hosting is not a suitable environment for all endeavours, and you may need more than the plan provides.

Yeah, what he said. Free hosting is great for things like testing scripts in a semi-controlled remote environment, designing and testing sites out of the public eye (during what I call their "ugly" phase) before moving them to a client's webspace, and small, low-traffic sites or personal/business homepages, but a lot of what people tend to use it for isn't what it's really intended for, like trying to run a social networking site or streaming media site with lots of users. Add to that the fact that free means everyone flocks to it, and it can be a real problem for some sites, having to share not only space but resources with thousands of other users.

Kind of like having too many windows open at once and getting a screen freeze on a laptop, but it's like the laptop is being used by everyone in the coffeehouse at once. And not everyone who drinks coffee knows how to go easy on a laptop. Okay, weird analogy, but it's past my bedtime.

Infinite (or more realistically, unmetered) bandwidth and space isn't a guarantee of unlimited processor resources. Especially when so many people want it at once.

My moodle simultaneous load is only 20 users max. That really shouldn't tax the server that bad. I've been running moodle on various servers that have had less memory and CPU horsepower. What would be the culprit when 5 or more just try to log in? I'm stumped.

You're actually not having really any significant usage on your account...

(the values are %CPU, %MEM, MySQL processes)

When are some peak times when users are on the site so that we can look at some in-depth logs?

Just had class of 18 log in at 12:50am EST and only one got in. The rest had message that the connection was reset. Then I had them log in 1 at a time and they were able to access the site. This has to be a server side issue right?

I'm gonna have to go with what was said earlier in the ticket -- upgrading to Illuminated or Premium hosting.

Moodle is a very resource intensive script. I monitored your processes during that time period, and you jumped up to a pretty high memory usage when your users were logging in.

I'm really not trying to "sell" you our premium services -- your needs exceed what free hosting can give you.
