--- Comment #2 from shaosong.li@salesforce.com --- When we are doing testing with symas-openldap V2.5.16, we have the err=52 when our traffic is high, about 100k per minute. It seems the requests are waiting in the queue since the max connection is limited to 256.
That is not what this parameter controls. I asked you very specifically - why do you need more than 256 concurrent *superuser* connections? This limit doesn't affect regular user connections.
We are using PingDirectory Service now, which has the max connection pool set to 7k and we don't have the issue there.
There is no connection pool size limit for regular connections in back-ldap.
So we are wandering if we could increase the conn_pool_max to a higher number such as 5k to see if we can resolve this issue.
No.
Make sure your nfiles ulimit is high enough.
There is nothing to fix here, closing this ITS.
