Dear FME Community,

since recently i have trouble with FME on parallel processing. When the first feature enters any custom transformer i get an FME appcrash. Also, I get different error messages on the same workbench, which is very unusual.

-------------------------------------------- Error_msg begin ------------------------------------------------------------

Error 1(most frequently):

|WARN |0arning: not all FMESessions that were created were destroyed before shutdown. This may cause instability

 

|WARN |Warning: not all Stashed Objects that were registered were dropped before shutdown. This may cause instability

 

|FATAL |Precondition failed at stfspec.cpp:1152. Expression: aFeature != 0

Error 2:

|ERROR |This FME edition does not recognize the `TransporterFactory' factory. Please ensure that the current platform supports this factory, the factory name is spelled correctly, and that you have installed all required plug-ins

 

|ERROR |A fatal error has occurred. Check the logfile above for details

 

|ERROR |f_5(TransformFact): Transformer 'multi': Unable to create worker; parallelism level may be too high for the translation requested

Error 3 (since last re-installation, newest one):

|FATAL |Insufficient memory available -- error code was 14 - please read the FME Help section 'Adjusting Memory Resources' for workarounds.

-------------------------------------------- Error_msg end ------------------------------------------------------------

The errors occurs on different versions (2016.1.3.1, 2017.0.1 build: 17288 WIN64).
As far as I can remember on FME 2015 or 14 it worked fine. Normaly i run
the *.fmw (@1thread) with python (subprocess) in parallel (@8 threads) , which still is working fine (*knock on
wood*).

FME (oracle edtion) is installed on Win7 Pro (inkl all servicepacks) on Xeon E5-1650 v3 with 64gb RAM (-->3rd error cant be true, redline is not manipulated), 1TB NVMe ssd and 12GB RAMDISK.

My Admin has tried some reinstalltions, with no effect. Also i tried to remove the sys-variables (os.environi'PATH'] = ''.). On other machines the workbenchs working without any problems. Only on my machine FME is crashing (even minimal tests) :/

Could some intel-drivers of the ssd make some trouble? or the ramdisk? We don't know whow to solve this problem and have no more ideas. Also i cant find similar problems in the knowlede center.

Thanks a lot for any hint,

Martin
