Greetings,

The good news is I was able to pull the necessary plugins out of git to get a coherent ptp_6_0 branch. I'm guessing they weren't available when I checked out master so they didn't show up on their own when I switched to 6.

I'm trying to run a profiling job on Yellowstone at UCAR now and getting this error and the stack trace copied below when ETFw attempts to run a command on the remote machine. I can monitor and run regular jobs without issue. Any thoughts? I assume the number of remote connections is not something I have any control over.

The error:

Yellowstone [wspear@xxxxxxxxxxxxxxxxxxxx:22] Opening SFTP connection failed. Does the remote machine support SFTP and multiple sessions? MaxSessions for the SSH server has to be set to at least 5. 4: received message is too long: 1131770477

Thanks,

Wyatt Spear
