2.6.1.1 Linux Operating System Notes

MySQL needs at least Linux Version 2.0.

Warning: We have seen some strange problems with Linux 2.2.14 and MySQL on SMP systems. We also have reports from some MySQL users that they have encountered serious stability problems using MySQL with kernel 2.2.14. If you are using this kernel, you should upgrade to 2.2.19 (or newer) or to a 2.4 kernel. If you have a multiple-CPU box, then you should seriously consider using 2.4 as this will give you a significant speed boost. Your system also will be more stable.

When using LinuxThreads you will see a minimum of three mysqld processes running. These are in fact threads. There will be one thread for the LinuxThreads manager, one thread to handle connections, and one thread to handle alarms and signals.
