If a PIprocess does not receive a response from the smsTrigDaemon process within 10 seconds, for a PI BPL command, then the PIprocess will time out the transaction and generate the following error message in the /IN/service_packages/PI/tmp/PImanager.log file.
BPL (Business Process Logic) functionality provides the ability to access the power of Advanced Control Services (ACS) functionality by using the PI (Provisioning Interface) to trigger a control plan (via smsTrigDaemon) on an SLC (Service Logic Controller) node (via xmlTcapInterface).
For further background reference reading on BPL please refer to the following documentation:

The PIprocess and smsTrigDaemon processes run on the SMS (Service Management Server), with the xmlTcapInterface process(es) running on SLCs.
