Package: mysql-server-5.1
Version: 5.1.49-3
Severity: important

I have a small script that will record in the database, some data.
http://pastebin.com/jcqfRnja

The file sparefile1.txt is stored such data at 14 MB
--- start file ---
insert into uc_spareshop_spare value('127628','xxx','xxx','1988','1995','xxxxx','','xxxxx','xxxx','','0','0','480','');insert into uc_spareshop_spare value('127630','xxx','xxx','1988','1995','xxxxx','','xxxxx','xxxx','','0','0','480','');insert into uc_spareshop_spare value('127629','xxx','xxx','1988','1995','xxxxx','','xxxxx','xxxx','','0','0','480',''); 
--- end file ---

My vps has 8G RAM 
If I run a php script that all memory is taken mysqld
12661 mysql     20   0  7g 6g 6364 S    2  1.3   5:18.81 7g mysqld

-mysqld.log-
120225 19:15:49 [ERROR] /usr/sbin/mysqld: Out of memory (Needed 14634160 bytes)
120225 19:15:49 [ERROR] Out of memory; check if mysqld or some other process uses all available memory; if not, you may have to use 'ulimit' to allow mysqld to use more memory or you can add more swap space

I tested that script on the mysql-server-5.0 and everything works without problems.
