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:

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?
