RE: areaDetector crashes EPICS IOC and autosave failure

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Hi Jong Woo,

 

You have not told us what version of ADEiger, ADCore, EPICS base, etc. you are using.

 

Ø  a) It keeps failing to open 'sseq_setting.req' file (Purple in the following message) 

 

Did you uncomment this line from ADCore/iocBoot/EXAMPLE_commonPlugin_settings.req?

#file "sseqRecord_settings.req",     P=$(P),  S=AcquireSequence

 

If so you also need to uncomment this line from ADCore/iocBoot/EXAMPLE_commonPlugins.cmd

#set_requestfile_path("$(CALC)/calcApp/Db")

 

Ø  b) It keeps failing to writing 'auto_settings.sav' file (Blue in the following message) 

Ø  ../save_restore.c(1774): [0xd]=write_it:Permission denied

 

That error seems pretty simple.  It is a file permission problem.  The files in that directory, or the directory itself, must not have write permission for the account that is running ADEiger application.  Fix the file permissions.

 

Ø  c) When the data acquisition is done on eigerDetector, it crashes EPICS IOC (Red in the following message)

Ø  Actually data hasn't been collected
Segmentation fault (core dumped)

 

You have a core dump file.  You need to run gdb on that to find where it crashed.

Run this:

gdb /path/to/ADEiger_executable core.xxx

 

where core.xxx is the name of your core dump file.  Once you get the gdb> prompt type this command

backtrace

Subject: areaDetector crashes EPICS IOC and autosave failure

 

Hello,

 

When the data collection is done on 'eigerDetector.adl', EPICS IOC is crashed and actually data hasn't been collected.

In addition, whatever parameters I changed on 'eigerDetector' are not applied in autosave. These are the summary followed by the message.

 

a) It keeps failing to open 'sseq_setting.req' file (Purple in the following message) 

     I made sure that this file has contents and it is in a right folder

          support/calc-R3-7-3/calcApp/Db/sseq_settings.req

          support/calc-R3-7-3/db/sseq_settings.req

 

b) It keeps failing to writing 'auto_settings.sav' file (Blue in the following message) 

     It keeps trying to save settings every 30 second as it is set on the first purple line. But it can't.  

 

c) When the data acquisition is done on eigerDetector, it crashes EPICS IOC (Red in the following message)

     Actually data hasn't been collected
