<div class="jive-rendered-content"><p>Hi, </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am using JBPM 5.2 for an application. I am facing issues when multiple threads complete work items parallely. These lead the process to completion and while completing, processInstanceInfo and a few other tables have DML statements executed. I use Oracle DB for the backend ! </p><p>Exception trace below. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Hoping someone can help. Do let me know what options i have. Things i gave tried </p><p>  - Increased INITRANS for the tables to 25 (default is 1) - This usually helps in ORA-0060 errors. However not this time <span> :( </span> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>====================</p><p style="min-height: 8pt; height: 8pt; padding:
