The quick fix is to ^Z, then fg, or kill -CONT the hung strace process from another vty. I don't know what strace does different from truss that makes it hang. Nowadays, truss does almost as good a job as strace, so I don't use it as often as I used to. The only thing I miss is strace's ability to print the name of blocking syscalls (read or sleep for example) as it waits. -- Dan Nelson dnelson@allantgroup.com
