Functions_search Fatal Error

[mrderanged]

Hey All,

Since just before upgrading to 3.5.1 (meaning this started happening in 3.0.7.), I have been having a sporadic problem with users getting the following error:

 Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 1024 bytes) in /home/includes/functions_search.php on line 196
  
 Call Stack 
 # Function Location 
 1 {main}() /home/newthread.php:0 
 2 build_new_post() /home/newthread.php:150 
 3 vb_datamanager_thread_firstpost->pre_save() /home/includes/functions_newpost.php:343 
 4 vb_datamanager_thread:[IMG]http://www.arachnoboards.com/ab/images/smilies/tongue.gif[/IMG]re_save() /home/includes/class_dm_threadpost.php:1457 
 5 fetch_similar_threads() /home/includes/class_dm_threadpost.php:1084 
 6 getsearchposts() /home/includes/functions_search.php:376

(path has been edited)

Now I'm not sure why this is happening as it is sporadic. Generally, if the user changes what they are naming the thread, then it will go though. I'm wondering if it's locking up when searching for similar threads. Could that be a possibility? Should I rebuild my search index? Can anyone think of why this is suddenly happening? I understand that it's running out of memory, but why has it started happening when it was fine with the amt of memory before? In other words, what could be causing it?

Any help would be greatly appreciated.

Thanks in advance,

Scott

Your php install is only allowed to take up 8mb per script execution, this search returned more than 8mb and it was caused to stop.

You need to up the memory limit to at least 12 if not 16mb

Hey Zachery,

Thanks for the super quick answer. If my host is not able to increase the amt of memory available per script, is there anything else that I can do? Would turning off the similar threads function help? Rebuilding the search index? Any further info you could give me?

Thanks again!!!

Turning off similar threads may help.

You can also enable the Fulltext search if you are on PHP 4.1 or newer.

Also having users get the following message when using the search (standard or advanced). Tried the same keywords "post ultimate" and got the same error...

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 35
bytes) in /home/search.php on line 1052
 
Call Stack 
# Function Location 
1 {main}() /home/search.php:0 
2 array_intersect () /home/search.php:1052

This the same issue or is something screwed with my search index?

Thanks

You've got users probally searching for really board terms like

"Word" and "Book" Which is returning alot of data.

Is it not possible to do what I suggested (up the limit) or switch to fulltext, or possibly both?

[mrderanged]

I'm waiting on a reply from my host about upping the limit. How do I switch to fulltext in the meantime? BTW PHP version is 4.4.0

[mrderanged]

my host upped the memory limit to 12 mb and that seems to have alleviated the problem. Thank you for your suggestions.
