i have problem mysql server (debian/lenny). mysql daemon fill memory , pages not accesible. restart of mysql daemon helps, have restart whole server (can't connect ssh anymore). here error log:

innodb: error: pthread_create returned 12<br/> 110228 23:58:36 innodb: started; log sequence number 0 43695
110228 23:58:36 [note] /usr/sbin/mysqld: ready connections.
version: '5.0.51a-24+lenny5' socket: '/var/run/mysqld/mysqld.sock' port: 3306 (debian).

edit

problem is, i'm not using innodb engine. tables in myisam engine. show engines says: no innodb. did before.

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
