Oracle Unified Directory (OUD) locked while importing data.
During the import of thousands of records (e.g., approximately 125k+ records) the OUD service stops and does not respond on its ports.
Testing a separate search while the problem is in progress shows OUD does not respond and it hangs, i.e., it freezes the entire server.
The problem happens consistently while executing the import of a file either into an ETL tool (e.g., Security Directory Integrator tool), or while running an LDIF with the ldapmodify command.
Following "Using RDA to Gather Debug Data for Oracle Unified Directory (OUD) (Doc ID 1474347.1)" and gathering jstack outputs of the hung process, e.g.:
Selecting the pid numbers for the ldapmodify command and the OUD server, then collecting jstack from them:
Note: If jstack does not work for the OUD process, add -F to the command, e.g.:
These outputs do not show anything obvious that can explain the problem.
