Bhumesh,
There is not enough information in your description to make any type of assessment of your problem. You have not mentioned what version of CAPAM and patch level your nodes are at, you have not included what type of setup you are using for the ssh sessions, is recording enabled, what do the Session log messages say, screenshots of errors, Java console logs or the Client logs.log.
Please do not reply further to this post, it would be better to open a case due to this not being something that can be worked on through this community post.
Regards,
Anthony
