Full Version: Out Of Memory Error

I am running 4.23 on a Unix-based shared web hosting service (aplus.net's Business web hosting plan). I have several blogs running off the same installation, two of which I use frequently. In total, there are 2,500 entries and about 775 comments. I have been getting, with increasing frequency, an out of memory error when publishing entries off the larger blog (2,063 entries) and now cannot publish any more entries in that blog. The index templates publish okay, but publishing an entry gives me:

QUOTE
Out of memory during "large" request for 4198400 bytes, total sbrk() is 59566080 bytes


Oddly, this does not happen with the other blogs on the same installation. I can publish entries in all the other blogs without issue.

Having searched these forums and the Intarweb, I've found a few similar problems, and most advice points to the server/hosting company. And that may be true here, though I wonder why it's affecting just the one blog. I do not speak "server," so I am not sure what to ask my hosting company to do (I either do not have "root access" or wouldn't know what to do with it if I did.) or how to fix it.

In other threads about this type of error, helpful folks asked for the results of mt-check.cgi. Here they are (I've bolded ImageMagick as that seemed to be a solution to some of the problems.):

The publishing templates are standard stuff. Here's the blog that's having problems, and here's the one that's publishing just fine.

Any advice for this non-technical guy? Thanks in advance, jb

Simply, publishing a bigger blog takes more resources. It sounds like your larger blog might be hitting the limit of the server resources available to you.

Some suggestions: use the publishing queue, template module caching, simplify complex template structures, remove slow plugins, etc. A more lean installation may improve things or completely eliminate problems, depending upon what your install looks like now.

Thanks Dan. I've turned on caching for the template modules. That alone has made no difference. I am working on a new individual archive template design that should be leaner on initial build. There aren't many active plug-ins.

For whatever it's worth, the number of bytes associated with the sbrk() is growing, more or less each time I try to publish an entry in that blog:

The server folks (aplus.net) have a trouble ticket going.

So I took the category entry count and monthly entry count out of the sidebar, and limited the category archive template to the last 36 entries, and rebuilt. It took only about 6 1/2 minutes to rebuild the 2,000+ entry blog. The other good news is, I can now publish entries again.

The bad news is, every category, date-based archive, search result, and tag search result all show the same entry, repeated over and over again, in the exact number of entries that should be shown. It's the most recent entry in the blog. Obviously one of my edits did something unwanted. I have no idea what. I'm having to take the blog offline until I can rewrite the templates.

It sounds like you may have enabled caching on an Entry Detail module. You need to pick and choose which modules and widgets get cached because some--like Entry Detail, Entry Summary and Comments--don't make sense to cache.

Thanks for the advice, Dan. I didn't have time to go through the module caching item-by-item, so I shut it off at the blog preference screen and republished. Though it took over 36 miuntes -- clearly uncached content comes at a performance price -- the archives, search results, and tagged entries results have been fully restored.

I also got a succinct email from the tech support at aplus.net telling me the script error has been fixed. No details were provided.

I made changes to my last entry and published it successfully, though it took awhile. Looks like I either need to cache content correctly or redesign the templates to use php includes instead of template modules.
