In Prod environment, we see few of the process gets stuck at startevent/service task, without any exception, Not sure why process gets stuck at this.
And it is not a async.
Sometimes i see process gets stuck at gateway too

Uploading the model would be helpful.
Also - how is the service task implemented? External Task? Java Delegate? etc.

@gowtham_m, In the exclusive gateway you have configured condition expressions like below:

${employmentType==domesticType}

${employmentType==internationalType}

If both of the condition not matched, then task will get stuck at the gateway itself. You need to add default flow also as the outgoing sequence from gateway. If none of the criteria matches, default flow will get activated.

@aravindhrs thanks, but in the above scenario, we always populate employmentType

6

For example, Consider below criteria:

employmentType = permanent, domesticType = contract

${permanent==contract} //condition failed

employmentType = permanent, internationalType = parttime

${permanent==parttime} //condition failed

If both conditions doesn’t match, process will get stuck.

The value of employmentType will be either domestic type or internationalType, it cannot be null and it can always have any one of the value as mentioned above

8

So domesticType and internationalType are not variables?

9

No, only employmentType is the execution Variable

10

then the condition should be like,

${employmentType == 'domesticType'}

${employmentType == 'internationalType'}

not like the below which will get evaluated both as variables.

${employmentType==domesticType}

${employmentType==internationalType}

Ya, but this is not causing the issue , as I see it’s evaluating properly

12

can you upload the java delegate configured in the service tasks? will be useful to find the issue. Both delegates: checkEmployerNameInEmpDbDelegate and ngtServiceDelegate

Is there any exceptions in server logs?
