I would like to find out where an application 'hangs' for some overly long time (possibly a network/socket call or something) Recently I grabbed out 'trace-1.6' for a HP-UX machine which is supposed to be based on the SUN kernel trace interface. The problem using the kernel option KTRACE would be that I cannot watch the application as it performs, instead I can only trace 'a posteriori'. Would the be a way to support this utility and the kernel trace interface under FreeBSD? Or are there any other ways (other than profiling, which is also an a posteriori method) to 'watch' what an app does? -- Chris Christoph P. U.
