 Dedicated server freezing intermittently, The three biggest dedicated of our cluster freeze and we need to force restart via hardware. (2 Replies, Read 14822 times)

Hello,

We recently purchased bigger servers with more ram and more powerful CPUs from OVH.

These servers are having an intermittent problem, they freeze every few days (sometimes 25, sometimes 2 (happened today)).

We still haven't found out the reason, no error log is registered, they simply freeze, they don't respond in the terminal (When we access via IPMI OVH), they stop responding to the ping, and they come back to work only with a hard rebot.

We have another 70 smaller dedicated ones, with 64GB RAM and Intel CPU, most of them using Ubuntu 20.04, and they never had this problem.

Has anyone here been through this, could anyone help us?

Dedicated Specs:
CPU: AMD Epyc 7371 - 16c/32t - 3.1GHz/3.8GHz
Memory: 256GB DDR4

Linux ns570494 5.4.0-144-generic #161-Ubuntu SMP Fri Feb 3 14:49:04 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

Here the last logs before the freezes/forced reboot:

How much is your SWAP memory?

We verified here that ours was at 25GB, which was very little... The problem may be related to this. We increased it to 150GB and continued monitoring. The problem hasn't reoccurred since then, but anyway the problem occurs every few weeks, so we won't know if it's resolved in a few weeks.
