Please do the following: ln -s AJ /etc/malloc.conf This will make the above warning fatal, and cause your inetd to dump core on the next occasion. Then, please analyze the coredump to find about where it was doing a bogus realloc(). You can also run it with -g debugging symbols, and with the -d option, in foreground in a gdb session. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
