Large number of ssh_poll/poll leads to "Interrupted system call"

["Dennis, Brent - 1008 - MITLL" <brent.dennis@xxxxxxxxxx>]

Hi,

I have an application which is trying to execute ~100-200 remote commands on multiple servers via libssh.  I can control the rate at which these commands are invoked (currently every ~5 ms).  Occasionally, the poll invoked by the ssh_poll() (rooted itself with an ssh_channel_open_session() ) returns with the "Interrupted system call" error, which ultimately corrupts my ssh_session such that subsequent ssh_channel_open_session() will also error out.

I tried to catch the signal that was interrupting the poll() but have been unsuccessful.  The problem is intermittent, but once it occurs, the session must ultimately be rebuilt.

Does anyone have any insight as to what could be happening?  Any ideas on how to narrow down determining the event which interrupts for the poll()?  Or are there any mitigation steps to take should this type of event occur?

Thanks,
Brent
