regular create and delete of buckets can lead to crash

Farshid Ghods added a comment - 01/Oct/11 9:29 PM - edited we do create/delete buckets more than 40 times during our BAT test run and we dont see the memcached crash anymore. 1- it can be the number of buckets the user is creating. 2- in windows the max number of buckets the user could create in 2.0 dp2 was i think 4 or 5. 3- memcached crash can also happen if user tries to create/delete buckets which have lot of data ( bucket-engine race condition which we have open bugs for ) I will take a look at test_bucket_max test and see if its passing or failing.

I think it's less about creating/deleting the same bucket, and more about possible resources not freed when creating new buckets even though the old ones have been deleted. The bug reporter says they're able to hang the system by destroying the last five and creating a new five buckets once an hour. It may be possible to do the same thing without the hour wait.

Keith Batten added a comment - 02/Oct/11 12:13 AM Our automated tests do delete/create quite a few buckets (apart from default, the bucket name is random though.) I'll look into loading a few buckets into DGM, then deleting and creating new ones, though I have never seen this cause problems before.
