Some problems with stability – JS Application Server
I have earlier done the script modifications in the template, a bit uncertain about the use of the multiplier though. In the remote task I have in the construct assigned a 60 minutes limit for inactivity and in the destruct I have assigned 1 minute. These actions seems to have resolved the problem so far – will stress test to the best of my ability during the following days.
One note though…
It is important that the same changes are made to the jstempl in the Omnis application html-folder since that eventually is involved in the creation of the js-forms dynamically created by the server. I also cleared out the earlier dynamically created js-files for the subforms and then starting the Omnis app server.
I am running macOS X Server with Apache and Postgres – do not think I can help in regard to the cron-jobs issue. Sorry… For those using macOS X Server it is a good idea to look into different parameters to increase performance of the server – Apple have really been setting the parameters low.
Take care, all the best…

> More notes on this:
> I’m running now into some other issues (where the server is running but user can’t connect), our OS server runs a number of cron jobs and handle web calls at the same time. I’m thinking that this is causing some issues with connecting to the web form when the server is busy with processing a job (which might be an http call to a third party API and might take a long time to get the response or when it process a long list).
> So I’m investigating now the option of separating the jobs from the web calls. I started installing 2 servers at some sites, one to handle web calls only and the other one (with no web configuration) will be dedicated to process the jobs, so any issue there won’t affect the web traffic. Still testing this approach.
> I also started installing a windows scheduled task on our sites to stop and re-start the Omnis serer once daily to make sure that the server is running until we manage to solve all its issues.
> I’ll appreciate if you could share any further solutions that you might find that help in solving the connection to your web app.
