I have this little problem on my server. Few times a week my server goes down for few minutes (2-3). All i could see was that every time one of the
php-fpm processes is on 100% in
As well as that our drive has a little write spike (by little i mean 4M throughput on 3disk SSD array.)
Server is running on NGINX + FPM, LEMP server. It has 24Cores, 48G RAM and 3xSSD's RAID5 array.
I have checked the error logs and other logs too, and there does not seem anything I could cache on ... It's been happening for over a week now, and I am starting to get worried.
Anyone have had any similar problems ? or could point me to some direction ? That would be lovely. Cheers.
