Significant increase in poller time after update from r11678 to r11831

After the latest stable update we have seen significant increase in poller times to Juniper MX104 devices. Before the upgrade the poller took about 100 seconds to complete and after the upgrade it takes about 260 seconds. 

I made rollback to previous release (r11678) and the poller times are down to what they used to be. 

Juniper MX104 routers are running version 19.4R1.10
