Subject [jira] [Created] (LUCENE-5556) scp to stalls during transfer
Date Wed, 26 Mar 2014 16:30:21 GMT
Steve Rowe created LUCENE-5556:

             Summary: scp to stalls during transfer
                 Key: LUCENE-5556
             Project: Lucene - Core
          Issue Type: Improvement
          Components: general/build
            Reporter: Steve Rowe
            Priority: Minor

When I first tried to build the first RC for 4.7.1 using {{dev-tools/scripts/}},
after preparing both the Lucene and Solr releases, the {{scp}} command to transfer the Lucene
release tarball to stalled after about 180MB had transferred out of 220MB.
 After an hour or so, I {{kill -9}}'d the {{scp}} process and started over.  Thankfully, everything
went smoothly the second go-around.

But I'd like to see if we can reduce the likelihood of this happening again.

I did some searching for causes/solutions to this problem and came across this recommendation
to use {{scp}}'s {{-l}} option to limit bandwidth in order to prevent stalls: []
- the recommendation there limits bandwidth to 1MB/sec ({{-l 8192}} is 8192Kbit/sec = 8Mbit/sec
= 1MB/sec).
