Hello,

 

doing an unindexed search with filter (uid=*ab*) the connection hang until the 389 Directory Server closes the connection after a long time (40 minutes or more) with error 11 (Resource temporarily unavailable).

 

After setting nsslapd-errorlog-level to 1 the following output was written to the error log:

 

389-Directory/1.3.3.10 B2015.141.1211

nsslapd-lookthroughlimit was set to 500. After looking through 500 entries the 389 Directory Server stopped looking through the entries and called "pagedresults_is_timedout" for a long time (40 minutes or more).

 

Why does the 389 Directory Server not sent an error message and disconnects immediately?

 

Kind regards

Gerd
