RE: Problem exiting IOC

["Jeff Hill" <johill@lanl.gov>]

Ø  If I exited the EPICS ioc-shell using the command, "exit", the problem appeared.

 

possibly it’s this bug

Hi Mark,

 

I too observed this condition only yesterday, and have not had a chance to investigate. I was using New Focus Pico motors, not MDrive hardware.

 

If I exited the EPICS ioc-shell using the command, "exit", the problem appeared. This would lead me to start my search for code that has hooked into the iocsh exit routines (atexit ).

 

Note: things appeared to shutdown cleanly if I exited with a ctrl-c.

 

Perhaps someone more familiar with those different code paths can comment further and narrow down the search...?

I'm yet another EPICS newbie. I've got a simple softIOC up and running
driving a couple of motors. Impressive software!
However I have a small problem. The IOC starts up fine and works
perfectly. But whenever I exit the IOC I get the following errors:

   epicsEvent pthread_mutex_destroy failed: error Device or resource busy
   epicsEvent pthread_cond_destroy failed: error Device or resource busy

My configuration is:
   Ubuntu 10.04
   EPICS base 3.14.12
   ASYN 4-15
   Motor 6-5-2

My st.cmd file is:

 #!../../bin/linux-x86_64/motorTest
 < envPaths
 dbLoadDatabase "${TOP}/dbd/motorTest.dbd"
 motorTest_registerRecordDeviceDriver pdbbase
 dbLoadTemplate("motor.substitutions") # Loads two records
 dbLoadRecords("$(MOTOR)/db/motorUtil.db", "P=IOC:")
 drvAsynIPPortConfigure("L0", "xxx.xxx.xxx.xxx:xxx",0,0,0)
 MDriveSetup(1, 10)
 MDriveConfig(0, "L0")
 cd ${TOP}/iocBoot/${IOC}
 iocInit

Any ideas on how I got into this problem? And what I do to get out of it
(and make sure it doesn't happen again)?

Thanks
Mark
