Red Hat Bugzilla – Bug 49968
tftp server locks up, stops serving files

User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.6 i686)
Description of problem:
Over time, the tftp server stops responding to new 'get' requests,
requiring a restart of xinetd. I sometimes see a 'connection refused'
message in the syslog, as noted in other bugzilla tftp reports currently in
Note: same problems exists in tftpd shipped with x86 RH6.2 .
Steps to Reproduce:
1. issue repeated tftp 'get' requests (for an existing file) with a script
(every 2 seconds)
2. tftp server will not reply to gets.
3. must manually restart xinetd
Actual Results: tftp server evantually locks up. xinitd reports the tftp
process is being attacked or the process has locked up. I am not attacking
the server, but the tftp daemon is hosed.
Expected Results: tftp accept connection, serve file, close, exit.
I will include test scripts (tcsh/expect) that I use to reproduce the
problem, and to automatically restart xinetd when tftp locks up.
Created attachment 24970 [details]
tcsh/expect scripts I use to detect/work-around the tftp server problem
Sounds very similar to the other mentioned bug. I'm already looking into it and
will close the other one as soon as i've fixed the problem.
Read ya, Phil
