Duplicate Collections!!!
Reinaldo
multiple collections with the same name into it.
echo "show collections" | mongo mongo01:30000/
aa895ca8156f4c7fa4104b1b4c9a8c38 | wc -l
10346
echo "show collections" | mongo mongo01:30000/
aa895ca8156f4c7fa4104b1b4c9a8c38 |sort -u | wc -l
450
mongo01 is a mongos connected to a cluster of 2 replica sets of 3
members each.
aa895ca8156f4c7fa4104b1b4c9a8c38 is the database name that is having
issues.
the java driver seems to enumerate ok the databases though, but
rockmongo does show the 10k+ entries.
The only "strange" thing but should not be a problem is that these
collections are dropped and sometimes dropped while there are inserts
going on, but is my understanding that it should just recreate it and
start inserting the data

Did you launch any map/reduce job ?

You were claiming that already on IRC last night but
you did not follow our recommenation writing some code for checking
the collection names through a small (non-Javascript) script/program.
Why not?

collections.
running a db.repairDatabase() fixed the issue, the exceptions and the
duplicate collections.
The names on the collections did not have any hidden characters not
according to the shell or the java program.

(which I think is a MR op anyways) Do you think that is the cause for
the duplicate collections ? In my setup something like this could
happen
1.- start a group op.
2.- collection gets dropped from another call
3.- inserts start happening so a new collection (with the same name)
gets created
