I removed the patch - the CloudLinux server was formally patched with KSplice, and the older servers were about to be replaced anyway and there's some debate as to whether it affects my kernel on those servers because they've been around a while.If you're having a problem with this, I'm sure cPanel wants to know about it. I suggest a ticket be put in and link them to this thread in the ticket.
For anyone who needs it, it's:
from https://access.redhat.com/kb/docs/DOC-40265If you need to remove the mitigation, run the following command as the root
user to restore the default behavior (and remove the above changes to
/etc/rc.local if made):
# echo -1 > /proc/sys/fs/binfmt_misc/32bits
Someone else can have their clients scream at them while they jockey with the temporary patch and cPanel support. I'm going to concentrate moving those servers to new CL boxes asap.
