Re: ferret keeps running in case of LAS errors



Martin,

Version 6.5 of LAS (which you've been having trouble installing) tries to address these issues.

In previous releases the LAS product server connected to Ferret and sent commands, waiting for Ferret to finish its work or send back an error message. If you requested the identical product a second time, before the first request had finished, the LAS product server started up another process.

In version 6.5 the LAS product server will always return something after <ui_timeout> seconds (see the release notes). If the product is finished it will return the requested product, otherwise the LAS product server will return a 'batch mode' page that allows the user to 1) monitor the progress of the result; 2) request email notification when it is finished; or 3) cancel the request. Multiple requests for the same product will no longer result in multiple processes recreating the identical product. Instead, additional requests will get the same 'batch mode' response that the first request got.

These modifications are designed to solve exactly the problems you are mentioning.

Hi,
I am confronted that ferret keeps running in the case of errors in ferret scripts. Moreover, also
if the access to LAS over the browser is finished it stays alive. Accessing LAS again and
encoutering another error a second instance of ferret keeps running. After some time these
processes occupy all memory and all processor power of the machine, driving it into pageing.

Finally all other processes freeze.

Does anyone know a solution?

Kind regards,
Martin Schmidt
