Re: MySQL 6.0.2-alpha and Falcon and possible bug/problem
Mathieu Bruneau wrote: I never tried the falcon engine, but could it be that mysql is running out of file descriptor ? That's less likely with Falcon than with engines that put each table and index in its own file. By default, Falcon tables share a single tablespace.

It would be interesting to get a stack trace at that point. We do have tests that create that many tables, so the problem is going to take some thought. I will try to re-run the same job, enabling falcon_debug_mask and see if I can get more info and repeat the problem. Sounds good - that can produce a LOT of output... so be sure to redirect it to a file.

Re: MySQL 6.0.2-alpha and Falcon and possible bug/problem
I never tried the falcon engine, but could it be that mysql is running out of file descriptor ? I think debian is limited to something around 8k per user by default. Check your pam settings and your ulimit ... Database usually use a lot of file handle and it's generally safe to increase it. Don't know if falcon use file handle per table or not tough... -- Mathieu Bruneau aka ROunofF === GPG keys available @ http://rounoff.darktech.org Mariella Petrini a écrit : I have re-run and job and I was able to repeat the problem.

Re: MySQL 6.0.2-alpha and Falcon and possible bug/problem
If Debian is limited to create files over 8k, it can be the reason of the problem. Falcon seems not create data file for tables, but still create .frm files for each tables. -- Jaemyung Kim 2007/9/9, Mathieu Bruneau [EMAIL PROTECTED]: I never tried the falcon engine, but could it be that mysql is running out of file descriptor ?

Re: MySQL 6.0.2-alpha and Falcon and possible bug/problem
I don't think that is the problem. I have been able to create over a 1,000,000 of tables with MySQL 5.1.21 and different storage engines with the same environment (I had already ulimit set).
