Description Felipe Zipitría 2016-07-29 14:55:10 UTC
Description of problem:

In version from upstream, squid 3.3.8 has a bug which keeps crashing the proxy server.

2016/07/25 11:56:36| assertion failed: "r->body_pipe != NULL" 2016/07/25 11:56:40| Starting Squid Cache version 3.3.8 for x86_64-redhat-linux-gnu...

Version-Release number of selected component (if applicable):


How reproducible: Always

Steps to Reproduce:
1. generate empty file ( e.g. : > empty.txt)
2. export ftp_proxy=http://<yourproxy>:3128
3. lftp -c 'open <yourftphost>; put empty.txt'

Actual results: Squid server crashes and restart. Your lftp client willl try to do the same in 30 seconds... so it will keep crashing your server until yo do something.

Expected results: Create an empty file in the ftp server, and the squid server keeps working.

Additional info: upstream already have corrected this bug:

Comment 4 Felipe Zipitría 2016-08-01 14:42:59 UTC
BTW, this problem happens also in squid 3.1.23 in RHEL 6. We ended updating our servers to 7 hoping the new version will address this problem, without success.
