问题
When calls bps service to create human tasks, I got following dead-lock exceptions.
The bps version is 3.2.0. The database is sqlserver 2012. Can somebody takes a look?
java.sql.SQLException: Transaction (Process ID 162) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

回答1:
Do you have a BPS cluster ? By going through your stack trace, dead lock was generated from Apache ODE engine when executing a job. With default clustering configuration, there is possibility of getting such deadlocks. This is known limitation in ODE 1.3.5 version and WSO2BPS 3.2.0.
However this is properly fixed in WSO2BPS 3.5.0. :)
https://wso2.org/jira/browse/BPS-675
https://github.com/wso2/wso2-ode/pull/7
My recommend is to migrate from WSO2BPS 3.2.0 to WSO2BPS 3.5.0 as it is straight forward. Following documentation describes migration steps.
