Hi,
Thanks for the info! I'm going to investigate it.
I didn't know of this Known Issue.
Apparently the connection losses of Switch itself and the Designer are caused by different problems.
With the support of the Enfocus Helpdesk we found out that the crashes of Switch itself propably happened because the programm is running into the memory limit of a 32 bit process. There are several things which might cause this:
Cause 1: PDF thumbnail generation.
In Switch 12, update 3 Switch asks the operating system to create thumbnails so it can send them to SwitchClient. In the case of PDF files the operating system asks Acrobat to create the thumbnails. Unfortunately Acrobat has a memory leak in the thumbnail generation process, causing the memory of Switch to grow until it reached the limit.
There are several ways to handle this:
Possibility 1: Upgrade to Switch 13, update 1
Starting from this version Switch creates the thumbnails for PDF files by itself, avoiding Acrobat and it's memory leak. If it is possible to upgrade to this version, then I would advise to do so.
Possibility 2: Manually adjust Acrobat to avoid the memory leak:
- Close down Acrobat
- Open the following folder:
C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat
- Rename "AcroRd32.exe" to something different
From now on it will use another process to generate the thumbnails which doesn't have the issue. Please note that after installing an update to Acrobat it will be necessary to do this again because Acrobat will have repaired it's own installation.
Cause 2: Keeping jobs for a long time in flows.
Please avoid keeping big amounts of jobs in flows for a long time. Switch keeps the job tickets of those jobs in memory, causing a major memory increase.
Cause 3: Loops in your Switch flows.
This may cause job tickets (which are kept in memory) to grow exceptionally large.
At the moment we are testing Possibility 2 and since the modification the programm didn't crash anymore
Now we only have to fix the Designer loss
But maybe the Known Issue helps.
Thank you!
