Random Crashes - stability tweaks

Postby tron2018 » Wed Aug 15, 2018 1:58 pm

Hi,

We have issues when running captures for an extended time, the server crashes. At that point we have to access our DRAC to reboot the server. We've looked at the server for issues. Updated NIC driver. Nothing in the event logs indicate what is happening.

I know this is an ad-hoc t-shooting tool, not meant to leave it running 24/7. But I was wondering what specific tweaks we might be able to do to for stability. Any thoughts or suggestions are appreciated!

Thanks,
Romeo

Hello-

As you stated, Omnipeek was just not designed for long term capture. We would encourage you to use the Capture Engine software instead, as it was designed for this. You can contact your account representative for details.

Here are some things you might try:

1. Disable all protocols from the capture adapter. They are not needed for capturing.
2. Uninstall any unnecessary applications on the server.
3. Disable all unnecessary services running on the server.


Hope this helps-

I applied some of the suggested ideas. It's hard to say if they helped or not...possibly.

Our server was end of support and we finally replaced it. Our new server is similarly spec'ed, but for whatever reason, I can run captures for days without issues, now. Of course there are several factors including how you filter the traffic, *if* you filter the traffic. But I always felt like it should be able to just keep on chewing up packets and saving them to disk. Worse case should be that packets are dropped. As long as the server and OS are stable, this application can be pretty solid.

some of the crashes can be hardware-related (bad RAM, ... These three simple tweaks can improve the overall stability
