Stricly spoken we don't have unindexed searches but my test bash script caused quite a number of. We are seeing random timeouts to this specific server when doing a search like the following: while true ; do ldapsearch -h ldapserver.company -ZZ -x -W -D "uid=johndoe,ou=people,dc=company" -b "dc=company" -L -y pwd ; sleep 0.5; done Watching the performance figures in the console does not highlight any specific problems. I am fairly certain that it is an internal network issue but I need to have proof which is why we are currently doing tcpdumps. We have only seen the problem on one of our consumer servers. The only difference being the order of servers in the nsfarmserverurl. Changing the order seems to fix the problem but as it is intermittent we can't really say that conclusively. Our chaining settings is quite aggressive though and might need further tuning. nsbindconnectionslimit: 5 nsconcurrentoperationslimit: 5 nsconnectionlife: 130 nsbindtimeout: 3 nsbindretrylimit: 3 nsmaxresponsedelay: 3 nsmaxtestresponsedelay: 5 Any thoughts on those values? Should/Could some values be increased?
