Hi guys,
I have a monitor system with zabbix 2.2.1 running well about 1 year.
Then this May,we've decided to deploy a distributed monitor system with 7 nodes,with a node 199 as master and nodes 11/12/13/14/15/16 as childs.
This system running without problem over 2 weeks,now it has a little issues.

When a trigger was trigged,the frontend of the master node can receive the issue and displayed on dashborad.But when Im trying to check events history by clicking the events menu,there is nothing.
After checking out all of the child nodes,I found that just node 13 and node 16 got that problem,by checking the log file with command tail -f /var/log/zabbix/zabbix_server.log,Ive got these messages on my screen:

And then,I googled this message and found a solution here:
https://support.zabbix.com/browse/ZBX-7452

this tips said that there's a patch for the issues,but when I was trying to apply the patch on my child nodes,I found that there's no such file"./src/zabbix_server/trapper/nodehistory.c",My zabbix was installed by command "yum install" from a rpm package,so there's not any source code on my server for this patch to patch it.

Up to now,I still have no idea to fix that problem,that's why I'm asking for help here.
BTW:I've just realized zabbix 2.4 has removed node mode,it means that the official team knows about this bug,so ,what the fxxx......
