Re: slapd core dumps on ldap add
Celalettin KILINÇ wrote:
Hi,
I have openldap 2.4.36 installed using mdb backend on Solaris 10. I am using
this database for a while and suddenly I started getting core dumps while
trying to add any data to database. Disk, memory usages seem fine. Database
size is not exceeded, it is almost 1/10 full. What may be the reason for this?
Please find the other information about the issue as below:
Loaded symbols for /platform/SUNW,Netra-T2000/lib/sparcv9/libc_psr.so.1
Reading symbols from /lib/sparcv9/ld.so.1...(no debugging symbols found)...done.
Loaded symbols for /lib/sparcv9/ld.so.1
Core was generated by `./slapd -d5'.
Program terminated with signal 10, Bus error.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
Doesn't look like any crashes we've seen before, but your best bet would be to
slapcat the DB and upgrade to a current version. (2.4.39 was released more
than 6 months ago, 2.4.40 release candidate is in testing now.) Ideally test
against the 2.4.40rc and see if the problem remains.
To be precise - slapcat your DB with your current version, then install the
new version and load a new copy of the DB with the new slapadd.
