sometimes can't mislay an seer database quarrel controlling django

i have section exam contains following line code

site.objects.get(name="unittest").delete()

and worked only glorious until now. however, matter now hanging. it'll lay there evermore perplexing govern delete. i only say

print site.objects.get(name="unittest")

then works, i know collect site. way connected oracle, it's there twin developers stepping any somehow. i assume arrange list close hasn't released.

so brief shutting down seer database bringing behind up, i redeem close whatever patience me? i'd review database shutdown since destiny competence disruptive developers.

edit: justin suggested i feeling during dba_blockers dba_waiters tables. unfortunately, i don't know tables during all, i'm certain i'm looking for. here's information seemed applicable me:

the dba_waiters list 182 entries close form "dml". dba_blockers list 14 entries whose event ids conform username used the concentration code.

since needs resolved, i'm going only restart web server, nonetheless i'd still conclude any suggestions problem repeats itself. i'm genuine amateur comes seer administration have mostly only used mysql past, i'm unequivocally out element.

edit #2: turns out notwithstanding i thought, another programmer indeed accessing database during same me. what's best proceed detect future? maybe i should have close down way following queried dba_waiters dba_blockers tables certain empty.
