Join them; it only takes a minute: Sign up What is SQL Error: 5, SQLState: HY000? and what can cause this error? up vote 0 down vote favorite The application I'm debugging writes randomly/occasionally this exception in its logs. org.hibernate.util.JDBCExceptionReporter - SQL Error: 5, SQLState: HY000 and an SQL out of memory error associated to this. While I found in mysql documentation what SQLState: HY000 is, I can't find anywhere what SQL Error 5 is, related to this state. Currently I know only that the db connection closes due to this out of memory error, and that the situation doesn't follow any pattern. Due to the nature of the program adding additional logging messages is not an option. (I can't do that as the application is huge and from what I've seen it happens randomly - different memory size needed for the queries to execute (in the messages) varying from 3 MB to 6 MB). Any help/information about this exception is appreciated. Additional information: It seems that the out of memory messages come in blocks of 6-50+ requests in an interval of 100-150 milliseconds. From a list of about 20-30 error messages, only 3 also appeared in mysql logs, the rest only in tomcat logs (printed the stacktrace).

SQL Error 5 is Out of memory. Review your query, increase buffers in my.ini. Also make sure to repair all your tables and re-index them.

I guess this indicates that I am reaching the upper limit of the 64MB allocated to me in my current MySQL environment. Does this mean that a single query is going over (returning) 64MB of data? If so, i guess i can just track down and tune that specific query? Or isnt that the correct http://stackoverflow.com/questions/3031636/sqlstatehy000-general-error-5-out-of-memory-needed-4194092-bytes approach? php mysql memory share|improve this question edited Apr 17 '11 at 18:17 user212218 asked Jun 13 '10 at 8:55 Jon 1491213 same error form me. –Thoman Jun 13 '13 at 9:44 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote Appears it failed to allocate about 4 MB of data during the query. You may be able to see this in the log output, such as with slow_queries. It's most likely a SELECT query, you may be able to find it by doing this in a near parent directory: grep "SELECT" `find | grep "php$"` share|improve this answer answered Jun 14 '10 at 3:54 Kristopher Ives 2,71342348 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

The servers match except for the fact 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 out of memory 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. One thing I'm thinking of trying is just rebooting the server to see if that fixes it. If it does, it may indicate issues with memory leaks. ?? Any suggestions would be appreciated. EDIT 1 These are the results from running ulimit command (both servers have the same results) prod:/etc# ulimit -a -f: file size (blocks) unlimited -t: cpu time (seconds) unlimited -d: data seg size (kb) unlimited -s: stack size (kb) 8192 -c: core file size (blocks) 0 -m: resident set size (kb) unlimited -l: locked memory (kb) 64 -p: processes 26303 -n: file descriptors 1024 -v: address space (kb) unlimited -w: locks unlimited -e: scheduling priority 0 -r: real-time priority 0 linux mysql memory share|improve this question edited Mar 5 '14 at 18:29 asked Mar 5

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
