http error 500 after system upgrade (mariadb)

ocsinventory-ng server on a Debian Stretch.

After the last system upgrade

(Install: libconfig-inifiles-perl(2.94-1), Upgrade: mariadb-common(10.1.26-0+deb9u1, 10.1.37-0+deb9u1), mariadb-server-core-10.1(10.1.26-0+deb9u1, 10.1.37-0+deb9u1), mariadb-server-10.1(10.1.26-0+deb9u1, 10.1.37-0+deb9u1), mariadb-client-10.1(10.1.26-0+deb9u1, 10.1.37-0+deb9u1), mariadb-client-core-10.1(10.1.26-0+deb9u1, 10.1.37-0+deb9u1), libmariadbclient18:i386 (10.1.26-0+deb9u1, 10.1.37-0+deb9u1)

all agents now receive a http error 500:

in /var/log/apache2/error.log I see these errors, for every agent connection tried:

DBD::mysql::dr connect warning:  at /usr/share/perl5/Apache/DBI.pm line 213.
[Mon Nov 26 11:44:49.289317 2018] [perl:error] [pid 352] [client] Can't call method "rollback" on an undefined value at /usr/local/share/perl/5.24.1/Apache/Ocsinventory/Server/System.pm line 282.\n

ocsinventory-ng server version is 2.5, and agents versions are from 2.3.1 to 2.4

Is there a fix for this? Thanks

I'm getting the same error:  Can't call method "rollback" on an undefined value at /usr/local/share/perl5/Apache/Ocsinventory/Server/System.pm line 282.\n

For me, the fix was correcting the "PerlSetVar OCS_DB_PWD" field in the z-ocsinventory-server.conf file, to the password that was entered during the install.

Thank you Andrew,

I double-checked, and both z-ocsinventory-server.conf and mysql uses same password for user "ocs".

I decided to hold the mariadb update until new updates will be available.

Did you restart apache after mariadb update?

Yes, and I rebooted the ocs server.

I also did the following steps:

  • mysql_upgrade -u root -p
  • mysqlcheck -u root -p --auto-repair --check --all-databases

Similar problem here with “OCS 2.6 RC” on “Debian 9.6” after an update from libmariadbclient18_10.1.26-0+deb9u1 to libmariadbclient18_10.1.37-0+deb9u1

apache error log:
[Wed Jan 09 11:03:00.792545 2019] [core:notice] [pid 5971] AH00052: child pid 15999 exit signal Segmentation fault (11)

Temporarily fixed using:
apt-get install libmariadbclient18=10.1.26-0+deb9u1
apt-mark hold libmariadbclient18

Any updates in this?
