Leif Hedstrom commented on TS-729:
----------------------------------
I assume there's no chance you will be able to test v2.1.7 ? Also, do you know
which line it's crashing on ? And what the values on parameters and local
variables are?
> Seg faults within HttpTransactHeaders::insert_via_header_in_request
> -------------------------------------------------------------------
>
> Key: TS-729
> URL: https://issues.apache.org/jira/browse/TS-729
> Project: Traffic Server
> Issue Type: Bug
> Components: MIME
> Affects Versions: 2.0.1
> Environment: X6240 Sun Blade (AMD64), 64G of RAM.
> Reporter: Ricky Chan
>
> Getting reports of regular seg faults on the traffic server CDN farm, in 1
> site 7 out of 10 servers have segfault at least once in 24 hour period.
> Traffic volume is low around 6 MB/s across all 10 servers. The idea was to
> put more traffic onto but I need to resolve this first.
> Okay I stipped the binaries so the core dump information isn't as help as it
> could be but it indicates the issue happened inside
> insert_via_header_in_request.
