Re: [Maria-developers] MariaDB 10.0.6 using more file descriptors than 5.5 ?

I've just migrated MariaDB (+tokudb) from 5.5.33a to 10.0.6, and I've encountered a '[ERROR] Error in accept: Too many open files' error during a backup. As this was not occuring with MariaDB 5.5, is this expected to have 10.0.6 using much more file descriptors ? (open_files_limit was set to about 8100 with 5.5, I raised it to 65535 now to fix this issue).

I'm vaguely remember (but failed to find a corresponding Jira issue), that InnoDB's async i/o used quite a lot of file descriptors. Perhaps that, together with TokuDB, used up all your 8100 descriptors. Regards, Sergei
