Hi, We have a three node mongodb cluster (with one arbiter) where every couple of days, mongod service on the primary restarts itself without any apparent reason. I have the following entry in the logs:
There is nothing before the shutdown signal in the logs (just normal operation). Nothing weird in SAR logs (processor, memory, disk usage normal), no log messages in /var/log/messages. It just looks like as if somebody restarted it manually but in fact nobody did, there is no indication of that in command history. Mongodb version: 2.6.4-1 Any idea why this is happening? |

Hi koitautomation@altegrity.com The logs you have uploaded indicate the mongod received a got signal 15 (Terminated) and as a result the mongod is exiting normally. As you note, this signal is most commonly received when someone runs kill <pid-of-mongod> as described in Stop mongoD Processes->Use kill. Please investigate what is sending this signal to the mongod. Since this issue is not indicative of a bug in MongoDB server, I will be closing this ticket. For MongoDB-related support discussion please post on the mongodb-users group or Stack Overflow with the mongodb tag. A question like this involving more discussion would be best posted on the mongodb-users group. Kind regards, |
