We had an issue where a single thread was using all the CPU. We wanted to check it at the command line while troubleshooting. We used what is below… $ jstack 3000 | awk '{if ($1 == "\"Thread-9\"") {i = 1;print $0} else if (i == 1 && $0 != "") {print $0}... »

Normally, without conflict detection and resolution, each update would be replicated to the... »
