Running a CiviCRM query at http://pastebin.com/6M1emH14, I get ERROR 5 (HY000): Out of memory (Needed 1640964 bytes) Though I can submit a query
In Memory Mysql Unit Test
change recommendation to CiviCRM, I'm hoping this can be fixed by adding an index or changing a parameter in the my.cnf file. Should I increase key_buffer_size or table_cache or is it another parameter? An InnoDB parameter perhaps (CiviCRM tables are all InnoDB)? +----+--------------------+-----------------------------------------+-----------------+------------------------------------------------------------------------------------+------------------+---------+---------------------------+--------+------------------------------+ | id | select_type | how much memory for mysql table | type | possible_keys | key | key_len | ref | rows | Extra | +----+--------------------+-----------------------------------------+-----------------+------------------------------------------------------------------------------------+------------------+---------+---------------------------+--------+------------------------------+ | 1 | PRIMARY | contact_a | index | NULL | index_is_deleted | 1 | NULL | 149732 | Using index; Using temporary | | 1 | PRIMARY | civicrm_group_contact-605 | ref | UI_contact_group | UI_contact_group | 4 | step2_crm_db.contact_a.id | 1 | Distinct | | 1 | PRIMARY | civicrm_group_contact-608 | ref | UI_contact_group | UI_contact_group | 4 | step2_crm_db.contact_a.id | 1 | Distinct | | 1 | PRIMARY | civicrm_group_contact-612 | ref | UI_contact_group | UI_contact_group | 4 | step2_crm_db.contact_a.id | 1 | Using where; Distinct | | 7 | DEPENDENT SUBQUERY | civicrm_group_contact | unique_subquery | UI_contact_group,FK_civicrm_group_contact_group_id | UI_contact_group | 8 | func,const | 1 | Using where | | 6 | DEPENDENT SUBQUERY | civicrm_value_1_riding__circonscription | eq_ref | unique_entity_id,FK_civicrm_value_1_rid

However, I tried to up it anyway and it did no good. I then tried to execute the statement in MySQL Workbench and I got essentially the same thing: Error Code 5: Out of memory (Needed 1073741816 bytes) I should have plenty of RAM to complete these operations (enough to fit the whole table I'm selecting from), but I'm guessing there are various settings I need to tweak to take advantage of all my memory. I'm running an Amazon EC2 High Memory Double Extra Large Instance with a Windows Server 2008 AMI. I've tried fiddling with the my.ini file to use better settings, but for all I know I might have made things worse. Here's a dump of that file: [client] port=3306 [mysql] default-character-set=latin1 [mysqld] port=3306 basedir="C:/Program Files/MySQL/MySQL Server 5.5/" datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/" character-set-server=latin1 default-storage-engine=INNODB sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" max_connections=100

Join them; it only takes a minute: Sign up out of memory error out of from mysql up vote 1 down vote favorite 1 we have a web application (racktables) that's giving us grief on our production box. whenever users try to run a search, it gives the following error: Pdo exception: PDOException SQLSTATE[HY000]: General error: 5 Out of memory (Needed 2057328 bytes) (HY000) I cannot recreate the issue on our backup server. The servers match except for the fact out of memory that in production we have 16GB RAM and our backup we have 8GB. It's a moot point though because both are running 32 bit os's and so are only using 4GB of RAM. we also have set up a swap partition... Here's what i get back from the "free -m" command in production: prod:/etc# free -m total used free shared buffers Mem: 3294 1958 1335 0 118 -/+ buffers: 1839 1454 Swap: 3817 109 3707 prod:/etc# I've checked to make sure that my.cnf on both boxes match. The database from production was replicated onto the backup server... so the data matches as well. I guess our options are to: A) convert the o/s to 64 bit so we can use more RAM. B) start tweaking some of the innodb settings in my.cnf. But before I try either A or B, I wanted to know if there's anything else I should compare between the two servers... seeing how the backup is working just fine. There must be a difference somewhere that we are not accounting for. Any suggestions would be appreciated. mysql linux out-of-memory share|improve this question asked Mar 5 '14 at 16:17 dot 2,93615417
