thanks bernard, that sped me along. i'm admittedly pretty green to debugger's in general, and i'm not quite sure if there's special kung fu in debugging a process's signal handler as it, if i understand signals correctly, is installed on a different stack.
i: - start gmond -d2 in one term - attach to the running gmond process - set a breakpoint for both apr_terminate and apr_pool_destroy - continue ....gdb will hang while gmond runs it's loop, the non-forked gmond window confirms that it's looping periodically collecting metrics and sending them off - send gmond a TERM signal, i get this from gdb: Program received signal SIGTERM, Terminated. [Switching to Thread 140540029593328 (LWP 11780)] 0x0000003121ed50d8 in epoll_wait () from /lib64/libc.so.6 ...maybe that thread is the signal handler? not sure. it occurred to me that gdb could be interfering with the SIGTERM, so i added: (gdb) handle SIGTERM nostop ...but this changed nothing. i also notice that if i set the breakpoints and left gmond running in gdb longer, i'd start hitting apr_pool_destroy.c:716 for every metric as it was being sent out(as confirmed by the interactive gmond window) i could continue for each breakpoint, but this just repeated...i'm not sure if i'm actually discovering anything here.
