Just some comments, I remember at one point in the past we had issues with the pop3d (1.2 series, and this was quite some time ago) that did something (I think maybe went silly, somewhere in the signal handling) that just went away at a later date after a kernel update, and we attributed it to a linux kernel problem (I think when series 2.4 was pretty young, don't remember exactly). I don't think anyone else had the same issue, and I remember it being somewhat consternating. Seems like there was also a similar issue that was "fixed" by compiling with -fomit-frame-pointer .. you might try that if you haven't. -- Jesse Norell - [EMAIL PROTECTED] Kentec Communications, Inc.
