pt-stalk output

spgriffinjrspgriffinjr EntrantInactive User Role Beginner
Hello

I'm troubleshooting issues with our mysql database and i have been running pt-stalk to output anything over 30 queries. There is a file that it keeps producing with this error:


[[email protected] (prod) percona]# cat 2013_05_16_18_44_40-opentables1


2013_05_16_18_44_41 Too many open tables: 1221


[[email protected] (prod) percona]#


[[email protected] (prod) percona]# cat 2013_05_16_18_44_40-opentables2


2013_05_16_18_44_41 Too many open tables: 1221


[[email protected] (prod) percona]#


I'm confused as this limit is way higher than 1221

global variables:


| table_definition_cache | 800 |


| table_open_cache | 2048

Before table_open_cache was set to 1024 and pt-stalk was showing too many open tables at 1025 and it was consistently showing that. Is there another setting I might be missing?




Any help would be greatly appreciated.

    Check open_files_limit variable and OS limits like that:
    cat /proc/`pgrep mysqld$`/limits
