[389-users] Connections hanging for unindexed searches

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 ... [30/May/2015:16:34:57 +0200] id2entry - => id2entry(498) [30/May/2015:16:34:57 +0200] id2entry - <= id2entry 34c1510, dn "uid=kenz,ou=people,dc=ukl,dc=uni-freiburg,dc=de" (cache) [30/May/2015:16:34:57 +0200] id2entry - <= id2entry( 498 ) 34c1510 (disk) [30/May/2015:16:34:57 +0200] - re_exec (kenz) 0 [30/May/2015:16:34:57 +0200] id2entry - => id2entry(499) [30/May/2015:16:34:57 +0200] id2entry - <= id2entry 19752c0, dn "uid=martens,ou=people,dc=ukl,dc=uni-freiburg,dc=de" (cache) [30/May/2015:16:34:57 +0200] id2entry - <= id2entry( 499 ) 19752c0 (disk) [30/May/2015:16:34:57 +0200] - --> pagedresults_is_timedout [30/May/2015:16:34:57 +0200] - <-- pagedresults_is_timedout: - [30/May/2015:16:34:57 +0200] - re_exec (martens) 0 [30/May/2015:16:34:57 +0200] id2entry - => id2entry(500) [30/May/2015:16:34:57 +0200] id2entry - <= id2entry 7f0c5c3711b0, dn "uid=martinj,ou=people,dc=ukl,dc=uni-freiburg,dc=de" (cache) [30/May/2015:16:34:57 +0200] id2entry - <= id2entry( 500 ) 7f0c5c3711b0 (disk) [30/May/2015:16:34:57 +0200] - re_exec (martinj) 0 [30/May/2015:16:34:57 +0200] - --> pagedresults_is_timedout [30/May/2015:16:34:57 +0200] - <-- pagedresults_is_timedout: - [30/May/2015:16:34:58 +0200] - --> pagedresults_is_timedout [30/May/2015:16:34:58 +0200] - <-- pagedresults_is_timedout: - [30/May/2015:16:34:58 +0200] - --> pagedresults_is_timedout [30/May/2015:16:34:58 +0200] - <-- pagedresults_is_timedout: - ... 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?
