That's probably because vi incorrectly interprets that as a multi-byte encoding, since it contains garbage. That's supposed to be a string restricted to those chars that are allowed by generalized time, so you shouldn't rely on vi guesses based on their actual, erroneous content. > In fact each time > the problem occurs I repair my database using a BDB C program wich reads > the first key from id2entry.bdb and writes it on disk. > Then I use vi to fix the contextCSN, before writing the key back to the > database. > Using vi I do not delete any characters.

The 08 you see in your broken entryCSN is the month, not the last two digits of the year. > Another precision : when the first two chars take corrupted, the rest of > the contextCSN gets stuck and does not follow write operations. > >> I note that, according to the sid values you assigned to servers A and >> B, the first contextCSN should not appear, since it has sid == 0, >> while the second one, apart from the corruption, is plausible (as >> you're writing to server A, with sid == 1). >> > Yes. > The contextCSN with sid=0 is there because at the beginning I initiated > my directory without SID (defaults to 0), then I set two difrent SIDs > for A and B. Can you try a fresh reload of the database(s) stripping out the entryCSN and letting slapadd generate them, using the -S <SID> switch (along with the -w switch), in order to enforce a SID of 001 (or 002, as you like)? p.

More information in the included > logs Sounds like a duplicate of ITS#5581, which was only partially fixed in 2.4.11. This should already be fixed in HEAD, please test. Also, try removing the brackets from the filter in the constraint_attribute statement; this should work around your issue while upgrading. p. Ing.

I am running windows 32 bits.

consumer crashing provider
by Dick Visser 27 Aug '08

27 Aug '08

(first post) Hi guys I am trying to set-up a pair of directory servers. Both of them run Ubuntu 8.04, which has OpenLDAP-2.4.9. I started out with one server, configured that to suit my needs (store UNIX and smb accounts), which works fine. Next thing is to set-up a second 'slave' server. After reading the docs, I decided to go for the syncrepl style replication for our micro tree. Everything seems to work fine. If I start the consumer it nicely pulls content from the provider. Retrieving the whole tree with ldapsearch from both servers yields exactly the same ldif. Great. However, if I now change something on my main server a.k.a. provider (f.i. change a password), the next time the consumers contacts the provider, the provider crashes: root@ldap:/etc/ldap# slapd -f slapd.conf -g openldap -u openldap -d 15 [snip] *** glibc detected *** slapd: free(): invalid size: 0xb676ef08 *** ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6[0xb7c62a85] /lib/tls/i686/cmov/libc.so.6(cfree+0x90)[0xb7c664f0] /usr/lib/liblber-2.4.so.2(ber_memfree_x+0x4a)[0xb7f93b4a] /usr/lib/ldap/syncprov-2.4.so.2[0xb787619a] slapd(overlay_op_walk+0x34)[0x80da4e4] slapd[0x80daaf7] slapd(fe_op_search+0x313)[0x8078a73] slapd(do_search+0x777)[0x80792e7] slapd[0x807653f] slapd[0x8076c36] /usr/lib/libldap_r-2.4.so.2[0xb7fa4714] /lib/tls/i686/cmov/libpthread.so.0[0xb7d4b4fb] /lib/tls/i686/cmov/libc.so.6(clone+0x5e)[0xb7ccde5e] ======= Memory map: ======== Aborted A slave server killing a master sort of defeats the whole purpose ;-) Any ideas how to solve this?
