I know what you meam

I know what you mean.. quite often I start up a mysql daemon, or something similar and get 5, 6 or even 7 identical processes... here is a snip of what I get right now when I $ ps -ef | grep mysql:


mysql 1545 1522 0 Jul29 pts/1 00:00:00 /usr/local/libexec/mysqld --base
mysql 1547 1545 0 Jul29 pts/1 00:00:00 /usr/local/libexec/mysqld --base
mysql 1548 1547 0 Jul29 pts/1 00:00:00 /usr/local/libexec/mysqld --base

bah!

that was menna be a reply to stealthelephant's thread about rogue processes

sorry!

- you can delete posts by pressing the "edit" button
- this is normal behaviour on linux. for accepting several connections, some programs spawn several processes (not threads like on windows) since then they can run on different CPUs or even different machines on a cluster

linux has a mechanism called "copy-on-write" for memory, in short words:
two processes that are use the same data use the same memory for reading and only if they write data, they require more and separated memory - cool, eh?

linux doesnt use threads in the same way other OS's do, it creates "shallow" processes doesnt it? and they are like threads for it
