We’ve already confirmed its BuddyPress. The sess files are not generated when buddypress is off. But im not even sure that’s the primary issue at work, it could be something else I am unaware of…
Thanks for your quick response. Has about 3000 users. The users have the ability to create Groups, upload avatars, etc. There are about 100 Groups. I noticed that it seems to be filling up our /tmp/ folder with billions of sess files so I increased /tmp/ folder to 8GBs. I used to get alerts as that folder would fill up, but now it just crashes without warning. We have 8 active sites on our server, only three of them are resource intensive, including this one. We also have WooCommerce store on the suspicious0bservers.org site. Any more info I can provide please let me know.
