MySQL hogging memory after upgrade

Hi,

Since upgrading to the latest Release version, MySQL is running a process that is hogging RAM and doesn't seem to end.

In top it shows as:

15032 mysql 15 0 523m 117m 4012 S 11.6 11.7 9:02.68 mysqld

And it just runs until it's stopped.

In the process viewer, it shows it as doing this:

getsockname(16, {sa_family=AF_FILE, path="/var/lib/mysql
"}, [28]) = 0
fcntl64(16, F_SETFL, O_RDONLY) = 0
fcntl64(16, F_GETFL) = 0x2 (flags O_RDWR)
fcntl64(16, F_SETFL, O_RDWR|O_NONBLOCK) = 0
setsockopt(16, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported)
futex(0x8512084, FUTEX_WAKE, 1) = 1
futex(0x8512080, FUTEX_WAKE, 1) = 1
futex(0x8512370, FUTEX_WAKE, 1) = 1
select(5, [3 4], NULL, NULL, NULL) = 1 (in [4])
fcntl64(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0
accept(4, {sa_family=AF_FILE, path="¨ƒ"}, [2]) = 872
fcntl64(4, F_SETFL, O_RDWR) = 0

Does anyone have any idea what is causing this? It's chewing up a LOT of memory!

Azza.
