DMC-853 GridFTP session reuse + PUT / GET through the same connection hangs

Situation

  • GridFTP session reuse is enabled
  • The remote endpoint supports the GETPUT extension

Symptoms

  • When uploading and then downloading a file through the same connection, the download process freezes, potentially causing a timeout.

Cause:

  • Globus denies it being a bug on the Globus Toolkit: Issue 57
  • Maybe a bug in dCache?

Workarounds:

Disabling GridFTP session reuse avoids these timeouts. It can be done programmatically, if you can not modify the configuration files:

ctx.set_opt_boolean("GRIDFTP PLUGIN", "SESSION_REUSE", False)
