What OS is the best platform for MySQL ?

[Blog Tieng Viet]

Dear All,
 
I have been using MySQL on FreeBSD for 3 years and encounterd a lot of problems related to
thread management. And 1 year ago, I found that my FreeBSD box does not go well with any
MySQL revision after 5.1.17-beta, because the MySQL thread does not end although complied
with LINUX_THREADS.
 
Now I want to chane platform for MySQL from FreeBSD to another OS.
Is there any advice for choosing OS?
 
Thanks in advance.
Best regards.
