Limit maximum processes - whats a good value

Hi,

what is a good value for preventing fork bombs and limiting max processes?

when i do ulimit -u i see 62570 which seems to be a high value to me.

pgrep -wcu $USER gives me the value 150 back.

is this ok or should i limit this? And if, what would be a good and practicable value?

Thanks
