since last week i noticed very strange smbd behaviour.
i have one samba PDC and three BDC's all connected to LDAP.
the PDC is the LDAP master and the BDC have their own replicated LDAP
since last week i notced that there are smbd processes on every DC which
perform never-ending LDAP searches for
the slapd logfile told me that everytime an entry was returned.
later i saw that there are also never-ending searches for
in this case an entry is returned too.
i get a whole lofgfile from smbd conatining these lines:
[2005/01/31 15:25:35, 0] smbd/server.c:open_sockets_smbd(388)
open_sockets_smbd: accept: Software caused connection abort
for every search request, smbd is opening a new LDAP connection, so i have
now about 800 smbd -> LDAP connections on every DC as there are a lot of
LDAP search request per second!!!
i have not seen this before samba-3.0.10. on friday i upgraded to
samba-3.0.11pre2 but it did not help anything.
the latest release notes did not point to any change in the ldapsearch
is there a new virus that i have not found which causes samba to perform
these LDAP searches or is this a serious bug?
thanks for any suggestions
The beginning is the most important part of the work.
