I would like to explain again my problem that I can reproduice very
I have 3 running scripts: each script executes a specific ldapsearch and sleep 1s ...etc
each script scans all the database!
The database contains 10000 subscribers (that is 30000 dn)
I launch too a script which simulates a high CPU use!
and approximately 1h30 afterwards the ldapsearch requests are altered that is instead of 11ms per request we have 15 seconds per search request
and even if I stop my script which simulates a high CPU use (so the
CPU use becomes again normal),
my search requests take always long time (15 seconds in average)
Then if I execute the "db_recover -v" command in my database and I restart
my openldap server
Again my search requests take a correct time (11ms in average)
I don't understand what the traces of the "db_recover" command
means ?? => cf. traces_recover file in attachment
I used too the command "db_printlog" to make printable the log files but it's the same pb
So my question is: which issue/exit do I have ?
1. go on anlysing traces but how doing ?
2. try to configure BDB backend but how doing ?
3. replace my BDB backend by LDBM backend ? where can I find a ldbm backend ...?
Thanks a lot
