what's mean waitport/waitmsg

[k simon]

HI,list:

    I noticed when I exec "top -S" ,some process's state display "waitport" or 
"waitmsg",
eg:
netisr_cpu 2   waitport
netisr_cpu 2   waitport
haproxy          waitmsg
squid              waitmsg

    What's this mean? Does it work normally?



Regards
Simon
