[Swift-devel] Strange errors while staging in data

[David Kelly]

Hello,

At the beginning of my run (apparently before any jobs actually start on
the scheduler) I am running into this error:

Swift 0.95 RC5 swift-r7605 cog-r3874

RunID: 20140301-1911-fe86tqf8
Progress: Sat, 01 Mar 2014 19:11:49+0000
Progress: Sat, 01 Mar 2014 19:11:50+0000  Selecting site:193  Stage in:307

Execution failed:
Exception in RunpSIMS:
    Arguments: [047, 438, params.psims, output/047/438output.tar.gz]

at
org.globus.cog.karajan.compiled.nodes.InternalFunction.run(InternalFunction.java:153)


This only seems to happen when I have 500 or more tasks. If I set
foreach.max.threads to a low number like 50, it seems to work fine.

The log is at
http://web.ci.uchicago.edu/~davidk/logs/RunpSIMS-20140301-1921-r4dps0i4.log.

Any ideas?
Thanks,
David
