Slapd stops processing queries or providing SSL certs

[William]

Hi,

Our slapd instance stopped responding to queries or processing queries
this morning. There are no errors in the log that aren't normal for
operation, nothing in abrt, and no apparent limits that we are hitting
up against.

Is this a known issue, or is there a way to start investigating this?
Any tips are appreciated.

Hi William,

it's a strange situation. What's happening at client side ?

If you take a

pstack <ns-slapd pid>

we could perhaps see what server is doing and try to diagnose why the requests are not processed.

Regards,

German.

They can't make queries. The sockets open, but SSL isn't negotiated.
openssl s_client hangs at

CONNECTED(00000003)

Sadly, we have restarted the instance in question already. However, if
it reoccurs I'll be sure to do this. I wanted to get some general tips
on how to debug the instance in case this does happen again.

Thanks.
