service ldap failed with message ch_malloc of 50272082776 bytes failed

[alpha041]

Hello everyone,

After a power outage, we were forced to run fsck on our zimbra server. After that operation the server started normally but everytime we are trying to start zimbra server

The ldap service constantly fail with this message in log :

Code: Select all

Apr 11 17:32:26 zimbra slapd[2839]: ch_malloc of 50272082776 bytes failed

I see that ldap is trying to allocate 46gb of memory and it is not normal. We have a small installation, around 400 users. 12Go of RAM.

Our version of zimbra : Release 8.8.15_GA_3869.RHEL6_64_20190917004220 RHEL6_64 FOSS edition, Patch 8.8.15_P9.

Can anyone help us resolve that issue ?

Thanks

Looks like the LDAP database is in bad shape, you should restore a backup/dump.

Hello and thanks for your reply

IS there a documentation that can guide me to do that ?

Do zimbra automatically make a backup ?

I have a backup of our server (2 months old) can i use it to restore ldap ? If yes is there a documentation to do that ?

Best regards

Hello Guys

My problem is solved. I used the solution mentionned in this link : viewtopic.php?t=57865

export the database and reimport it. Some account are missing. But it's another problem.

Thanks

You should read documentation (wiki) and make your own backups if you don't have the right version (Network Edition or OpenSource Edition + ZeXtras).

For deleted account here is the link i use to restore : https://wiki.zimbra.com/wiki/How_to_res ... _from_LDAP

And one more time thank you for point me to the right direction.
