Can't create a new thread (errno 12)

Hi All,

I’m facing the error in mysql - “Can’t create a new thread (errno 12);
if you are not out of available memory, you can consult the manual for a
possible OS-dependent bug”

Also, It throws the error like,

"090925 20:50:53 [ERROR] /usr/sbin/mysqld: Out of memory (Needed 1048583
090925 22:09:52 [ERROR] /usr/sbin/mysqld: Out of memory (Needed 132176
bytes) "

I those, Mysql asked me to use the ulimit to increase the size of its
elements to avoid these kind of problems,
so that, I have increased the open files limit in ulimit. it was 1024
before I changed as 2048.

Even so, My problem is not solved, When the mysql thread connection
increases because of lot of request to my application, Mysql starts to
throw this error.

I don’t know how to solve this problem yet. As of now, I have decreased
my wait_timeout as 10 sec. from 180 sec.

Please guide me through to get rid of this issue.

Thanks in Advance,
Sathish K.
