Sorry to step in this late in this discussion. I haven't got much time to track 
samba lists.
Just to let you know. I have exactly the same problem with 2.2.2 on HP-UX 10.20 
that was compiled by myself.
At first samba was crashing all the time. I tracked that down to malloc calls. 
That's right! I even installed the latest libc patch: to no avail. I finally 
hardlinked the libmalloc.a library and that problem went away.
Now I have the described behaviour. It also shows up with the connections error 
locking : delete_fn. LOGIC ERROR ! Entry for pid 969 and it no longer exists !

Currently I cannot take Samba down as that would crash some applications of 
users. I hope I can restart it tonight with debugging enabled to get an idea 
what's the cause of this.
Just an add-on note: I have this binary running on two machines. (untill now) 
It only shows up with the machine that is stressed by multiple users. The other 
machine is seldom accessed by more than one user simultaneously.
