[jira] Commented: (TS-147) Reverse Proxy Mode + Cache crashes /
Segmentation fault when using HTTPS dynamic pages, Static Fine
[ https://issues.apache.org/jira/browse/TS-147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12848864#action_12848864 ]
James Henderson commented on TS-147:
------------------------------------
I seem to be having the same issue, but with a static page under load. I am not getting the "SSL3_READ_BYTES:sslv3 alert certificate unknown" message though.
Environment: FreeBSD 7-STABLE on i386 using latest dev build
Backtrace:
Program received signal SIGSEGV, Segmentation fault.

Steps to reproduce:
1) create reverse proxy using ssl.
- remap https://<server> to http://<internal_server>
- enable reverse proxy (I set to use pristine host headers and require remap)
- enable ssl (I used a bogus self signed cert for testing)
2) Using httpperf to create load from another server:
httperf --timeout=5 --client=0/1 --server=<traffic_server> --port=443 --uri=/ --rate=200 --send-buffer=4096 --recv-buffer=16384 --ssl --num-conns=5000 --num-calls=10
It works for a few seconds and then segfaults.
