No, it is around 400
ps ax | wc -l 417 I also I increased max process to unlimited, and I still get the error randomly..
ulimit -u unlimited
my webserver is now throwing this error:
setuid(500) failed (11: Resource temporarily unavailable)
cat /etc/passwd | grep mark mark:x:500:500::/home/mark:/bin/bash I also increased this, but still the same error kernel.pid_max = 65536
