syslog-ng 3 (3.19.1)

Error Message:

syslog-ng[50418]: Error accepting control socket connection; error='Too many open files (24)'

I'm seeing this in the syslog-ng logs. However, I've done everything I can think of to increase the file handles and the number of open file handles does not seem to be anywhere close to the max. What else could be causing this?

Thanks,
