Dears,
the sitemap script has not been finished yet for several days, without any sitemap file on the output
we are set the Maximum execution time to 0 for unlimited time, but the script stopped working every 30 minutes and showed the screen to continue or start a new session
Attach PIC1
also, we have set a cronjob to invoke runcrawl.php every 30 minutes but it's the same issue,
on the server, the data directory has a lot of files but not sitemap.xml
Attach PIC2
if we rerun  Crawling and set to Continue the interrupted session it's works for about 30 minutes then it interrupted
Attach PIC3

Hello, 

in this case I would recommend to run generator in command line if you have ssh access to your server.
