[Swift-devel] Re: [VDL2-user] GridFTP timeout exception

[Tiberiu Stef-Praun]

How do I know that a GridFTP client timeout occurs ?
It seems that my SIDGrid workflow has stopped performing.
Normally it should process 200 parallel tasks, each of which producess
1GB  in 28 files.

I am testing with 0.1 rc 1, but the same has happened to me before
(SVn checkout, v0.rc3,etc).

The workflow freezes after a while (after processing the first round
of jobs submitted? = I received 16G and that's it). The current
scenario is me using 3 teragrid sites (UC, Purdue, NCSA), but the same
behavior (workflow freeze) happened when I ran the workflow on
teraport only. Since It hang, I was always forced to terminate it, so
we never had a full SIDGrid run.

Any suggestions ?

BTW, the NCSA problem is a non-issue, I solved it.  The only other
small issue is taking full advantage of all the sites in the
sites.xml. And the big issue is what I listed above.

Next I will try running the workflow fully at the UC teragrid site.
