Hello, Using Xymon 4.3.7 I see in my /var/log/xymon/xymonlaunch.log log file the following error: =================================== 2012-03-12 16:07:57 Loading tasklist configuration from /home/xymon/server/etc/tasks.cfg 2012-03-12 16:07:57 Cannot open directory =================================== This isn't too much use since it doesn't say what directory it is trying to open. It seems the problem is in the file lib/stackio.c (around line 338). A patch to fix this is here: ========================================== --- lib/stackio.c.orig 2011-07-31 22:01:52.000000000 +0100 +++ lib/stackio.c 2012-03-12 16:07:34.619479967 +0000 @@ -338,7 +338,7 @@ if (*dirname == '/') strcpy(dirfn, dirname); else sprintf(dirfn, "%s/%s", stackfd_base, dirname); if ((dirfd = opendir(dirfn)) == NULL) { - errprintf("Cannot open directory %s\n", fn); + errprintf("Cannot open directory %s\n", dirfn); return; } ========================================== (Sorry about the line wrapping.)
