"sleeping without queue" ?

[Mikhail Teterin]

Hello!

My attempt to build openoffice.org-3 seems to be hanging. Pressing 
Ctrl-T produces:

    load: 0.11  cmd: tcsh 79759 [sleeping without queue] 0.00u 0.00s 0% 0k

(tcsh is used by OOo's build-script). What is this "sleeping without 
queue" state, and why is process in it for so long?

This is an 4-CPU amd64 system with 4Gb of RAM. Only 16% of the swap is 
currently in use and the box seems to be perfectly fine otherwise. 
Uptime is 55 days, two different X-sessions are functional... The kernel 
is FreeBSD 7.0-STABLE #0: Sat Mar  8 16:02:37.

Thanks!
