Description

i am using mod_secdownload. every time someone request a file mulitple times lighttpd lock up and freezes, i have to restart lighttpd for the server to come back online.

i get several hundred request in a matter of mins for the same file, i am not sure if this occurs when someone is using a download accelerator? mod_secdownload tiggers the HTTP error 410, so i am not sure if the actual flood is 410 "gone" request or the actual file (since it's expired after a few minutes according to my settings).

happens about once or twice a day and lighttpd stays locked up and won't respond to requests until restarted. a little http flood shouldn't be locking up a Dual Quad 8GB RAM server.. what is the cause? kind of sucks the site can be taken offline by a simple download file flood. i had this problem in 1.4 also appears to have it since trying lighttpd 1.5

logs snip of flood (several hundred times):

any word on this? still having this problem... when person floods "GET" requests to download file, lighttpd just stops responding.. this is obviously a serious flaw in lighttpd and must be looking into imo..

Don´t use "High" if you aren´t sure it is a severe bug. So for now I assume it isn´t, as 410 is an answer - and the correct one btw. Else add a gdb/strace output on where lighty is crashing.

If it indeed freezes then it is high priorty. But I don't think it's mod_secdownload that is to blame.

Maybe the server is just running out of file descriptors? Who knows.

Please provide errorlog, gdbbacktrace and strace log when it locks up. Thanks

@scub: I realize this was a long time ago, but we need a little more information in order to try to reproduce this. Hopefully, this is not still an issue for you. :)

mod_secdownload is no longer part of lighttpd base distribution
For replacement, see mod_magnet and lua mod_secdownload
