Hi, I am using default openldap-server-2.3.27-5 coming with red hat 5 and I am using syncrep method to replicate with master ldap server. The replication itself worked well, was able to replicate a large database. but I have a severe problem that slapd process spikes high CPU every few seconds. User time is about 85%. The whole server gets very very slow.
I turned slapd to debug level -1 and grep for error. The only error i got was: ----------- -Oct 16 17:32:59 ldapserver slapd[3127]: => access_allowed: backend default search access granted to "(anonymous)" Oct 16 17:32:59 ldapserver slapd[3127]: <= test_filter 5 Oct 16 17:32:59 ldapserver slapd[3127]: <= test_filter_and 5 Oct 16 17:32:59 ldapserver slapd[3127]: <= test_filter 5 Oct 16 17:32:59 ldapserver slapd[3127]: bdb_search: 10555 does not match filter Oct 16 17:32:56 ldapserver slapd[3127]: ber_get_next on fd 24 failed errno=0 (Success) Oct 16 17:32:59 ldapserver slapd[3127]: connection_read(24): input error=-2 id=14, closing.

Oct 16 17:35:32 ldapserver slapd[3127]: connection_read(18): input error=-2 id=37, closing. ---------- (I do not know if this is related with high CPU), there was no particular messages in /var/log/message. I have 3.2GHz CPU and 2G memory on this server. Has anybody had the similar problem before? Can anyone advice what can be done in order to troubleshoot further? Thanks. Angie
