Description

Today suricata stopped after running for almost 9h:
May 27 12:05:22 server suricata28762: memory allocation of 4294966034 bytes failed
May 27 12:05:25 server systemd1: suricata.service: main process exited, code=killed, status=6/ABRT
May 27 12:05:25 server systemd1: Unit suricata.service entered failed state.
May 27 12:05:25 server systemd1: suricata.service failed.

Could not find a core file though I configured a home directory and core dump in suricata.yaml
As far as I can see the system was not running out of any resources.

Hi,
Thank you for the report!
Was this a default config run or there were changes made to the memcap/ring settings ?

Can you share some more details? Like suricata --build-info, the configuration file and it would be perfect if you can reproduce it with a coredump.

At https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Debugging you can find more information how to debug this.

Config file attached, maybe the settings are not correct to create a core dump because I was not able to find one after the crash yesterday?

How much memory you have on the box btw in total? (and is it only suricata running or something else that can be resource intensive ?)

64Gb RAM available and indeed an ELK stack consumes almost half of the available RAM, but this setup has been running for years quite stable. On the other we want/need to move the Elasticsearch setup to a newly to build cluster.

I think it is a good candidate reason in some conditions (aka an intense ES search) for not being able to have that needed extra allocation. In general yes - could be better if things are separated as i suspect resource contention would also occur(if not yet) in terms of CPU too.

I don't think this has anything to do with the system or what else is running on it. The error suggests suri tried to alloc almost 4GB in a single malloc, which is certainly a bug. It smells like an int underflow.

Indeed, but I had a look at some system resources when the crash occured, but neither Zabbix nor sar did mention lack of memory or cpu. Oke is is a busy system, but that keeps the dust away ;)

Running v5 since May second, it happend twice so far:

2019-05-27T12:05:22.331122+02:00 server suricata: memory allocation of 4294966034 bytes failed
2019-05-21T09:44:12.279565+02:00 server suricata: memory allocation of 4294926257 bytes failed

Suricata is restarted daily to rotate logs.

Is it possible to correlate the sys/ram utilization at that time ? Just to make sure it is not sys/mem related I was thinking.
