Subject: | Weird stream device behavior when using the IOC shell's exit function |

Hi We are using the following setup to test control of the agilent XGS gauge controllers and Gamma ion pump controllers:
1.
EPICS Base 3.15.6
2.
Asyn R4-33
3.
Stream R2-7-7c For agilent controllers we get the following error: asynError in write. Asyn driver says: device:port disconnected. But eventually the IOC exits. For the gamma controllers we get something really strange. There a point in the database where the IOC never exits, the exit command just freezes and
Ctrl-C is the only way to shut down the IOC. For now I can see that this behavior occurs because more DB substitutions are configured which means more PVs and more controllers. But that was not the case when we had:
1.
EPICS Base 3.14.12.3
2.
Asyn R4-18
3.
Stream R2-5-1 Where the IOC exits with no errors or freezing. Should we upgrade our support modules or change the EPICS base? Another problem we are facing with this new setup is that I can't find some asyn IOC shell function like asynTraceMask for example. The IOC is configured properly in RELEASE and src/Makefile.
Is there anything we miss in the new setup? Best Regards, Abdalla Ahmad Control Engineer SESAME Allan, Jordan. Tel: (+962-5) 3511348 , ext. 265 Fax: (+962-5) 3511423 Mob: (+962-7)88183296 |
