I'm doing some testing recently with perf_events(3.10) and postgresql 10.5 on centos 7.5 with kernel 3.10.0-862.3.2.el7.x86_64
On 1 terminal, I'm running pgbench against a postgresql 10.5 server
/usr/pgsql-10/bin/pgbench -c 1 -j 1 -T 10000 test -P 5
On another terminal, I'm getting the stats for static probes in postgresql with the following command.
perf stat -e sdt_postgresql:transaction__start,sdt_postgresql:transaction__commit -a -- sleep 60
postgres will crash upon running the perf stat command above
I have used gdb to try and capture the stack trace as below against the server process. I did try and attach to the postmaster process but it didn't generated any stack trace
Program received signal SIGILL, Illegal instruction.
