What kind of system are you running on? Linux / multiprocessor?
No, right now that's just my poor man's laptop (Intel(R) Pentium(R) M
processor 2.26GHz, UP) running Linux (2.6.18, CentOS 5.2). Tomorrow I
can check on better hardware, including SMP (quad Opteron), but I don't
think that's a problem. Of course it's using epoll().
Can you try a newer Linux kernel?
The last useful log entries are:
do_syncrep2: rid=001 (-1) Can't contact LDAP server
do_syncrepl: rid=001 retrying (4 retries left)
connection_read(10): no connection!
The do_syncrep2 message is printed at syncrepl.c:1208.
At that point both err and rc are -1. It'll fall into line 1217 and tear down
the connection, which would remove it from epoll's control. So I don't
understand why epoll is waking up repeatedly after that point, unless perhaps
there's a kernel bug in epoll...
