Full_Name: Ali Pouya Version: 2.3.36 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (145.242.11.4) My directory is formed with 4 servers syncronized through syncrepl (RefreshAndPersist). THe directory contains about 10 million entries in the BDB back-end. My slapd servers are configured with the default 16 threads. I have a JAVA injector for write operations. The injector establishes 28 connections to the master and writes about 1400 entries per minute. After several hours of activity the master hangs. It accepts TCP connections but does not handle LDAP operations. LDAP requests remain hanged until interruption by the client. The replicas are OK.
