Having it built in LSF will definitely help. Relying on LD_PRELOAD'ing a shared library at LSF startup is inconvenient at the least, for varous reasons like:
* external dependency
* unclear/undefined what will happen with child processes and LSF jobs
* harder to maintain
We will look at enabling this.
Keepalive is a socket option which must be enabled by the program. The kernel must support it, but it can *only* be enabled from within the program which opens the socket.
As a dirty hack, libkeepalive (http://libkeepalive.sourceforge.net/) could be used. However, I cannot see what side effects this has.
Is TCP keepalive enabled in the kernel on both masters? If so, the kernel should handle this automatically.
Creating a new RFE based on Community RFE #63295 in product Platform LSF.
