Question regarding openldap 1.2.11 error messages

[Daniel.Erdoes@net-and-works.de]

Hi wizards,

we get some strange error log messages on two of our ldap slave servers:

1)

May 24 06:10:59 paloma19 slapd[21103]: [ID 266667 local4.info]
ldbm_db_errcall(): ==> Unable to allocate 1071 bytes from mpool shared
region: Not enough space
May 24 06:10:59 paloma19 slapd[21103]: [ID 266667 local4.info]
ldbm_db_errcall(): ==> unable to create/retrieve page 2318
May 24 06:10:59 paloma19 slapd[21103]: [ID 266667 local4.info]
ldbm_db_errcall(): ==> PANIC: I/O error

This host has 512 MB memory. Most of the memory was unused at the same
time.

2)

At the same in time in the slurpd log of our master server we got error
messages which refer to (2):

Our environment:
openldap 1.2.11 on Solaris 8 x86, sleepycat 2.2.7
One master server and a few slaves.

Does the error messages mean that the database could be inconsistent? Could
it help to update to the latest release 1.2.13?

Thank you very much in advance.

Daniel
