Sometimes multiple instances of ScheduledThreadPool objects getting created on single session - which we tried to avoid by making scheduler static as above. 2. ProcessContext data getting corrupted with duplicate process instance info. When we print out the session & process info from context  in our registered custom timer service  - its showing duplicate process instance ids as shown below. +*ProcessJobContext processJobContext = (ProcessJobContext) ctx;*+ +*StatefulKnowledgeSessionImpl ksessionImpl = (StatefulKnowledgeSessionImpl) processJobContext.getKnowledgeRuntime();*+ +*System.out.println("**********>session id : "+ ksessionImpl.getId() + "; process id : "+ processJobContext.getProcessInstanceId());*+ **********> session id : 0; process id : 6 **********> session id : 0; process id : 7 **********> session id : 0; process id : 8 **********> session id : 0; process id : 9 **********> session id : 0; process id : 10 ...................... **********> session id : 0; process id : 6 **********> session id : 0; process id : 7 **********> session id : 0; process id : 8 **********> session id : 0; process id : 9 **********> session id : 0; process id : 10 These processes 6 to 10 are getting scheduled twice & executing twice.+* *+ -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/793026#793026] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
