Zabbix server crash when doing history cache sync during shutdown

    Details

      Description

      Zabbix server crashed when exiting because of low history index cache size:

      Apparently during hc_update_history_queue() the history item hashset contained items without data (NULL tail/head values). It's not clear yet how it could have happened. The initial error (insufficient history index cache size) can't be direct cause.

      Current theory is that after the exit of the initial process server sent termination signal to the rest processes and one was aborted in the middle of new item adding to history cache, however unlikely it would seem:

      		item = hc_get_item(item_value->itemid);
      
      		/* new items must be inserted in queue */
      		update_queue = (NULL == item->tail);
      
      		if (NULL == item->head)
      			item->tail = data;
      		else
      			item->head->next = data;
      
      		item->head = data;
      

      If a process was killed right after item = hc_get_item(item_value->itemid); then we would have history item with NULL tail/head values.

        Noticed a server crash during testing.

        Test scenario:

        • 10000 hosts;
        • hosts have 1 item (agent.ping) from the linked template;
        • HistoryIndexCacheSize=256K (you might have to change this a bit);
        • after changing the interval from 30s to 5s the server crashed.
        • the scenario for a proxy is symmetrical.

Test scenario: 10000 hosts; hosts have 1 item (agent.ping) from the linked template; HistoryIndexCacheSize=256K (you might have to change this a bit); after changing the interval from 30s to 5s the server crashed. the scenario for a proxy is symmetrical. 21377:20160317:174620.314 Starting Zabbix Server.

        The cause of the crash is an error in __binary_heap_ensure_free_space(). It stores the number of allocated binary heap elements before the allocation. If the allocation fails then other processes can read or write past the allocated shared memory for the binary heap. In our case this happened with history queue which is stored as binary heap in history index cache shared memory. This issue has been latent since the initial implementation of binary heap back in 2010 but it was discovered only now after implementing ZBXNEXT-3071.

        However there is a more serious problem. If the server has run out of history index cache memory then the final synchronization is not possible as well. This is a regression of ZBXNEXT-3071.

        The solution for the crash is trivial.

        The solution for the final synchronization problem is non-trivial. Perhaps the simplest approach is to store the history queue in heap memory instead of history index cache's shared memory during the final synchronization.

        Fixed a memory corruption caused by failed memory allocation when inserting element in a binary heap in r59205.

        Reduced the risk of failed final history synchronization due to exhausted history index cache memory in r59285.

        The remaining failure mode - the main server/proxy process runs out of heap memory during final synchronization. The maximum HistoryIndexCacheSize=2G.

        The attached python script adds 10000 hosts via API. You'll have to adapt the program to suit your environment.

        New issues related to this problem:

        • ZBX-10630 - Protect cache integrity by blocking signals for critical sections;
        • ZBXNEXT-3233 - More controlled exit (server, proxy).
