Can you try the rpm at http://people.redhat.com/teg/xinetd/ and see if it makes any difference?
installed new rpm from http://people.redhat.com/teg/xinetd/, so far no problems :> - it's been running for ~ 1hr, still monitoring....
Much the same problem, but with wuftpd: Redhat 7.1 , xinetd 2.3.0, Kernel 2.4.6.: FTP server does 5k to 9k transfers a day. Jul 18 11:14:03 ftp xinetd[3451]: {bad_signal} Received 10 signals in 1 seconds. Exiting... Jul 18 11:14:08 ftp xinetd[3452]: {bad_signal} Received 10 signals in 1 seconds. Exiting... I tried to overide the default of 10 by adding : [root@ftp sysconfig]# pwd /etc/sysconfig [root@ftp sysconfig]# more xinetd # Add extra options here EXTRAOPTIONS="-loop 25" but this didn't help either. I will try the suggested RPM and report.
Installed 2.3.0-2.1.rpm last night Still seeing the following in log this morning: Jul 19 08:10:23 ftp xinetd[9329]: {general_handler} (9329) Unexpected signal: 11 (Segmentation fault) Jul 19 08:10:23 ftp last message repeated 9 times Jul 19 08:10:23 ftp xinetd[9329]: {bad_signal} Received 10 signals in 1 seconds. Exiting... XINETD is still spawing new ftp sessions, transfers completing. Users probably getting intermittent "Resource unavailable."

Same behavior on RH7.2 with xinetd-2.3.11-1.7x. IMAP Connections are immediately disconected by the server with the same ("Segmentation Fault") message in syslog. Other protocols, for example pop3, are working. Restart doesn't help.
