HI Listers,
We had a situation where the load average spiked to more than 2000+ and continued the saw way for about 45 minutes. During this entire time we had CPU 95% idle. One thing that was observed was that we had a sudden increase in the number of connections from 1800 to around 3700. We had 90Gb of free memory throughout when the load average spiked.
Server has 48 CPU with 512 Gb of RAM running on RHEL 7.6.
Is this something expected?
Thanks,
Goti
