Hi, So here is a little anecdote from the real world. I was planning to update the OS on my Linux server, from Ubuntu 18.04 LTS to 20.04 LTS (Long Term Support). This small (Digital Ocean, 1GB RAM, 1 Core) cloud server runs 3 Pharo images with public facing web sites. The machine itself reports: $ uptime 12:37:50 up 530 days, 21:46, 1 user, load average: 0.02, 0.04, 0.01 which means it hasn't been powered down or didn't restart in 530 days. I was surprised to discover that 2 of the Pharo images on that machine did just as well: $ ./repl.sh Connecting to Telnet REPL at locahost:41011 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Neo Console Pharo-7.0+alpha.build.660.sha.2eb9bd2f41e7b0bd8f9f4190906910f83c178ab1 (32 Bit) pharo> get system.uptime 405 days 20 hours 29 minutes pharo> quit Bye! $ ./repl.sh Connecting to Telnet REPL at locahost:41001 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Neo Console Pharo4.0 of 18 March 2013 update 40620
get system.uptime 530 days 21 hours 44 minutes quit Bye!
So both Pharo 7 and Pharo 4 kept on doing their jobs for a very long time. I think this is a testament to the stability of Pharo and to what is possible. Regards, Sven -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org
