It seems that JNDI does not know how to correctly send an Unbind request...
Also I've dumped the received PDU and when we are hit by the problem (ie
LdapError 53 : bad cookie received), it shodws that we don't receive the
UnbindRequest fast enough, thus we get a BindRequest immediately
followed by a SearchRequest containing a cookie which is not reset. As
the LdapSession has been reset by the new Bind, the transmitted cookie
is obviously not present in this session, and we get the error we are
facing.
So far, it's absolutely normal, and I really suspect that this is a JNDI
problem. I have added an explicitely context close(), with no help.
My last test was to add a 10 ms wait after the ctx.close() in the
doLoop() method and it seems to be efficient.
I will try with the Ldap API to see if we are havig the same problem.

Good catch Emmanuel.
Maybe this [1] could be a reason (just from far away without any deeper
knowledge).

I still have random issues at this point, but less frequently. What
happens is that we receive a searchRequest with a cookie, just after the
previous request has been completed. I have no idea why. If I add a
Thread.sleep(10) in the doLoop() method of the test, I'm able to run
10000 times the paged search ( this is 40 000 paged search requests...).
I will try tomorrow the same test but using our API instead of JNDI.
Will keep you informed.
