Hi, I'm ports maintainer of pecl-trace 1, I has been updated phptrace to 1.0.0 and encounter this problem.

Run commands described in README as following show error message like ERROR: Invalid process id "54000" "No such file or directory(2)" But it's ok with phptrace -p all

php -r 'for ($i = 0; $i < 10; $i++) usleep(10000);' &
phptrace -p $!

Try it on the lastest FreeBSD, works as expected.

Screenshot

So, could you re-produce it? using these snippets below.

1. extend whole cost time

php -r 'for ($i = 0; $i < 20; $i++) usleep(50000);' &
phptrace -p $!

2. Specified pid

php -r 'for ($i = 0; $i < 100000; $i++) { usleep(50000); echo getmypid()."\n"; }'
# PID will be displayed by PHP, and phptrace -p $pid
