Subject: kernel BUG, kernel problem
Hello,
I have terrible problem with kernel 2.6.32.2. My server after running a
few days (3-4) system freeze. Sometimes I'm able to login but I can do
nothing (even execute any command). In logs I can see kernel crash. Here
is output:

Apr 7 07:38:07 s4 kernel: [httpd:23685]: failed fork with errno -12
by /usr/sbin/httpd
We can see there is some problem with creating new process. Errno -12
equal with 'Out of Memory' message which is strange. In kernel stack
trace we can see problem exists with playing work queue. In the source
code we are able to see that directive BUG_ON catch unexpected
situation:
"kernel/workqueue.c"
264 static void run_workqueue(struct cpu_workqueue_struct *cwq)
265 {
266 spin_lock_irq(&cwq->lock);
267 while (!list_empty(&cwq->worklist)) {
268 struct work_struct *work =
list_entry(cwq->worklist.next,
269 struct work_struct,
entry);
270 work_func_t f = work->func;
271 #ifdef CONFIG_LOCKDEP
272 /*
273 * It is permissible to free the struct work_struct
274 * from inside the function that is called from it,
275 * this we need to take into account for lockdep
too.
276 * To avoid bogus "held lock freed" warnings as well
277 * as problems when looking into work->lockdep_map,
278 * make a copy and use that here.
279 */
280 struct lockdep_map lockdep_map = work->lockdep_map;
281 #endif
282 trace_workqueue_execution(cwq->thread, work);
283 cwq->current_work = work;
284 list_del_init(cwq->worklist.next);
285 spin_unlock_irq(&cwq->lock);
286
287 BUG_ON(get_wq_data(work) != cwq);
I have no idea what can cause exactly this problem! Can you somehow help
me?
