Re: Application thread blocked on procnto
To give some more insight ....The application thread launches a "sh" process, which inturn launches a "sftp" process and
"sftp" inturn launches a "ssh" process for communication.
The application thread calls popen() with the following command string.
sftp -oPasswordAuthentication=no -oStrictHostKeyChecking=no -oNumberOfPasswordPrompts=0 -oPort=22 -oIdentityFile=FILE.
ssh.prv userID@IP
After it successfully launches the above commad, we see 3 processes in a normal working scenario.
388177965 proc/boot/sh
388177967 usr/local/bin/sftp
388182064 usr/local/bin/ssh
In the scenario, where we see the thread getting reply blocked on process "1"
we see the following processes.
388177965 proc/boot/sh
388177967 usr/local/bin/sftp
388182064 (Zombie)
It is clear that SSH is getting killed and becomes a Zombie. But, we are not sure why SSH is getting killed abruptly
Does anyone had a similar experience while using sftp/ssh application????
Any help is appreciated.
