https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18615 Bug ID: 18615 Summary: LDAP configuration error causes server resource depletion under Plack Change sponsored?: --- Product: Koha Version: 16.11 Hardware: HP OS: Linux Status: NEW Severity: normal Priority: P5 - low Component: Authentication Assignee: gmcharlt@gmail.com Reporter: helpdesk@neci.edu QA Contact: testopia@bugs.koha-community.org CC: dpavlin@rot13.org When running with Plack enabled, it is possible to get KOHA to keep spawning processes until the hosts's resources are exhausted. The immediate upshot is that KOHA hangs, the final result is that all other services on the host eventually stop functioning as well. Steps to reproduce: Enable useldapserver and specify an empty search base in the ldapserver element: <useldapserver>1</useldapserver> <ldapserver> ... <base></base> ... </ldapserver> Restart koha-plack for the instance. The plack-error.log file starts filling up with "Compilation failed" errors on all modules that somehow invoke Auth_with_ldap.pm. The "top" command shows two active /etc/koha/plack processes owned by the koha-$instance user. Each process uses ~50% of the available CPU cycles. These processes are replaced continuously. ps aux | grep apache shows an every increasing number of Apache instances owned by the same user. Without Plack, the same configuration problem triggers an error page for KOHA, but the rest of the services on the host are not affected. -- You are receiving this mail because: You are watching all bug changes.
