My directory is formed with 4 servers syncronized through syncrepl
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.
strace is useless. Please get a backtrace of all the threads using gdb.
Make sure you compiled with debugging symbols, and that slapd is not
stripped. I'd also advise getting a backtrace on a current release, as
there have been a number of race conditions and cleanup fixes made since
2.3.36. You may want to wait on 2.3.41 which will be released in the next
