Hi, Finally I've managed to remove those strange extra lines from my logfiles: It turned out that /dev/log always gets 4096 bytes written to it, regardless of the length of the log entry - so I changed the MAX_LINE macro in read_line.h(libol) to 4096. I Also made a change to sources.c in the while (eol) loop in the function 'do_read_line'; after the call to do_handle_line I added the following lines: closure->pos = 0; return ST_OK | ST_GOON; This means that we will only log the first log-entry in the buffer, I think thats ok because the rest of the buffer seems to contain plain rubbish. Oh, I almost forgot; I'm using gcc on a HP-UX 11.00 system, libol 0.2.21, syslog-ng 1.4.4 Regards /stefan
