Linux下多个同名进程 高手请进

请问这是怎么回事，java有33个进程，mysqld有41个进程，参见截图
运行环境是rhel as3u5，应用程序实际使用，还没发现异常。
# uname -r;cat /etc/issue
2.4.21-32.ELsmp
Red Hat Enterprise Linux AS release 3 (Taroon Update 5)
Kernel \r on an \m

同样的应用程序，在rhl9和rhel as3u4上正常，java和mysqld进程各一个
# uname -r;cat /etc/issue
2.4.20-8smp
Red Hat Linux release 9 (Shrike)
Kernel \r on an \m

# uname -r;cat /etc/issue
2.4.21-27.ELsmp
Red Hat Enterprise Linux AS release 3 (Taroon Update 4)
Kernel \r on an \m
