Traffic Router Fails to Server HTTPs Requests

[Nir Ichye <ni...@qwilt.com>]

Hi,

I'm working with TC 2.1 (commit 3980b41797c8f2b616277df4b74e73a011c48869) and
DS that supports both HTTP and HTTPs.
All worked well and suddenly HTTPs requests got timeout while at the same
time HTTP worked well.

I sniffed on the client side and saw that the server doesn't respond with
Server Hello although the Client Hello packet was received (I can see the
ack).
Cap is attached.

After a while, I couldn't reproduce the issue anymore.
Unfortunately, I don't have a cap from the server-side and couldn't find
any clue for an issue in the logs.

Has anyone ran into this issue?
Any ideas what could have cause this and how to avoid it in the future?

Thanks,
Nir.

Thanks Dave.
Unfortunately, I can't reproduce this issue at this moment.

I haven't used the Tuning Recommendations from the docs. Will do!

Thanks!

Hmm...we did see this problem a long time ago (pre 2.0) where GC was
happening on the TR which caused HTTPS requests to stop.  Are you able to
reproduce?  If so, can you see what the box is doing while your requests
are timing out?  Can you check if that is when GC is running? Also, are you
running TR with the recommended settings from the docs[1]?

It looks like the file wasn't sent.

Thanks.
