Hi

I have a process which will/should never die. It basically runs as a daemon, and sleeps for random intervals. A script run thru crontab sends this process a SIGHUP every 5 mins, and my process does the necessary stuff.

It is imperative that this process does not die, as it holds important data in memory. To elaborate more, it basically polls SNMP devices for byte counters and stores the values in a database. If this process dies I lose around 3 polls of data.

Now what I needed was a way to re-execute this program so that I could enter some lines of code, more debugging statements, some bug fixes, etc. If I call exec "program" - maybe on some signal - then yes.. it does include the new code, but it loses the data in memory. Is there any known way of preserving the data and reloading the program from file?

Thanks a lot!
