Hi, This is a Solaris 9 (SunOS spdmze21 5.9 Generic_122300-13 sun4u sparc SUNW,Sun-Fire-V240), running syslog-ng 1.6.8. After my previous posts to the list, I managed to get 2 truss outputs, once showing the signal being received and processed and one showing the signal being received and nothing happening at all. Here is what happens when the signal isn't processed : /1: Received signal #1, SIGHUP, in poll() [caught] /1: poll(0xFFBFEC78, 329, 100) Err#4 EINTR /1: sigprocmask(SIG_SETMASK, 0xFFBFE81C,

Maybe one of you guys has an idea ? Thank you for any help!
